I wanted to reimagine Lego Batman's costume in a non-Lego context.

This is a drawing of the Sagat from Street Fighter, along with a few alternative outfits/colorings based on his  many game appearances.

This is a drawing of Joe from the very first Street Fighter game.

A simple caricature drawing of the three stooges, with added film grain and weathering to capture that 1930's-40's film aesthetic.

This is a drawing I made many years ago of Captain Falcon from the F-Zero video game series.

This is a character sheet for Poison Ivy that I created for a Batman fan comic I have written.

I designed this skin for a contest for the game Dead By Daylight. The design is a Scottish Olympic track and field outfit, since the Blight is a character who's gimmick is injecting himself with a serum to speed up, and enhance his abilities, hence the name.

This character is  "Ken" from the flash game, Bloody Rage. The character's in the game are all licensed, (this one is particular is Ken from Street Fighter) so the aim was to redesign them to be more unique and original.

This is a design for Robin that I created for a Batman fan comic I have written. This costume was designed to more closely resemble a bird. This can be seen in with elements like the cowlick in his hair, pointed nose on his mask, and splayed cuffs on both the gloves and boots.

This is yet another drawing of Batman. This one was a potential design for my Batman fan comic, putting emphasis of the animalistic elements of his costume.

These are a few animations I created for Evil Ryu for my fan game, "Battle of the Best". The trailer for the game, as well as more assets can also be found in this section.

These are some portraits I drew for Axel and Break for my fan game, "Battle of the Best". The trailer for the game, as well as more assets can also be found in this section.

I was tasked with designing the propeller motion, as well as the gun firing effects for this plane.

These are a few animations I created for Walter White for my fan game, "Battle of the Best". The trailer for the game, as well as more assets can also be found in this section.

This is the trailer for my fan game and side project, "Battle of the Best". It is a 2D, crossover fighting game featuring characters from many different franchises. I work with a small team and designed almost every aspect of the game and did most of the art myself. I did not however, create the music or code the game.

This a character named Pluto that I did the animation for during a Game Jam in early 2026. While I did animate the character, I did not design them. The game we put together is titled "StarCrossed". There is a gameplay video in this section as well.

These are some portraits I drew for The T-800, Shaggy and Scooby, and Batman for my fan game, "Battle of the Best". The trailer for the game, as well as more assets can also be found in this section.

This a character named Neptune that I did the animation for during a Game Jam in early 2026. While I did animate the character, I did not design them. The game we put together is titled "StarCrossed". There is a gameplay video in this section as well.

These are some portraits I drew for Ryu, Ken, Evil Ryu and Violent Ken for my fan game, "Battle of the Best". The trailer for the game, as well as more assets can also be found in this section.

These are some stages featured in my fan game "Battle of the Best". The trailer for the game, as well as more assets can also be found in this section.

This is the trailer for my Super Mario Bros ROM hack. I challenged myself to redraw all the graphics for the original Super Mario Bros, while working within the limitations of the original hardware. I ended up releasing it for download.

These are some sprites I created in an attempt to mimic the art style of the SNES video game "The Adventures of Batman and Robin". I made sprites of a handful of characters from the cartoon series not featured in the game adaptation.

This was an attempt to redraw the iconic purple Jason Voorhees sprites from the Friday the 13th NES game. I created these with the intention to replace them in-game, taking special care to draw them with the same limitations as the originals.

Here are a few conceptual animations I created to pitch my art overhaul of the indie game, "Super Box Ball Z". The pitch ultimately didn't go anywhere.

Here are a couple of animations I created many years ago for a fighting game character based on Oingo from Jojo's Bizarre Adventure. In the first, he is using his disguising ability to look like another character. The second animation shows him nervously walking away.

A couple of animations I made for the character, Tereon, for the indie fighting game "Ravage Fist" created by Radical Ronik.

This is some gameplay footage of the game I did the Animation and UI design for titled "StarCrossed" for the 2026 Global Game Jam.

This is a water color painting I made of the Ghost of Captain Cutler from Scooby-Doo.

I painted this after playing a lot of Doom. While not a painting of anything from the game, it is definitely inspired by its visuals.

A painting of the ending of Terminator 2: Judgement Day.

I painted this outside during a thunderstorm.

These are some of the UI elements for the game I worked on for the 2026 Global Game Jam.

Here are some UI elements I created for my fan game, Battle of the Best.
