Hello, spithas11!
1) Please upload all items in a single file by using file archiving.
2) I see that the asset cover is unclear. Make it more useful, that is my advice.
3) Make more assets if you want donations. Or do more challenging asset. Look: https://itch.io/game-assets/top-sellers/store/tag-pixel-art There's dudes have done the sweaty job, spend tons of time and ask for few bucks.
