The difference between the old one and this one is that this one is meant to look good in a game, and the other is meant to look good in other projects. I'll make this a spritesheet soon. EDIT: It's here!!! https://scratch.mit.edu/projects/1212948368/
I used my original vector as reference for things like his glove cuffs and socks, used a pixel Sonic sprite for the head, tweaked it a little, and yeah that's all. Thanks to Sega for creating the blue dude!
