Are these Super Smash Bros levels? If so, I can spot several things. I think you should try ti start our shading smaller things, as there are many unbroken expanses of colour as well as much pillowshading on both maps, especially the second.
As for the sprite, this is not a place where people try to "fix" your work for you but instead try to help you improve. If you mean edit, people do that here, but it is still meant as a learning exercise.
