Senku Niola's Sprites and Such

[Zapchu25]

I agree with Hoeloe. When blowing up your sprite, I can see random details like shoelaces or the glasses frame. When making a sprite, you want to focus on the things that the player really needs to see. For example, If he's a punching guy he'll usually have bigger hands, kicking guys have longer legs, etc. So unless these details are functional or add to the overall aesthetic, you don't really need them.

Also, your sprite has 25 different colours. This messes with readability. A sprite that size could probably get away with 16 or less. Heck, 16 may even be too much.
