look man i don't know much about the game and all but isn't the entire point of the game is that everybody gets a chance, not only is leaving the sprites to "veteran artists" incredibly demotivating, but the sprite is fine in it's own right
of course some sprites are gonna be better than others that's how art works, and if you don't like that then just make it yourself cuh
tldr: there isn't anything wrong with the sprite, you're just expecting 10/10 works from a COMMUNITY FOCUSED GAME
