The world of my sprites and pixel art

[NintendoFTW]

Thanks for the comments.

Are these traced? They look traced. They alos look flat, use your shades to add volume, actually these look like a beginner in photshop/gimp/some other program similar to those, first try at using said program. These don't really look like pixelart.

Yes, they are traced, cause that's the way I work and my thought on that's how most Pixel Arts are made. If I may ask, could you elaberate on what you mean by add volume?
