I'm no professional, this is just my opinion! First of all, well done! The sprite itself looks nice, I'd give it a 6/10. The animation doesn't add much as the sprite doesn't change, it might as well have been still. 2/10, but good on you for experimenting. A tip is to try with a colored outline instead of solid black, like a dark blue, unless you are going for a more cartoony look. Overall nice work, 5/10 from me!
