This is one of my first pixelarts, which I used to make with Hexels.
LONG LIVE FEZ
Yeah, it's because I didn't know anything about pixelart when I did this. Definitely 21 are too many colours xD
im not sure how you managed to use 21 colours for such a simple piece. you might want to condense that colour list and refine the piece overall.
keep at i!t!
