How can a novice like me, to improvements in my pictures? My friend mentioned the shadows, but I'm not clear what it means. And I know that my Pikachu is a mess, it's my weakness when it pokemon to create, I can not do your body down for some reason.

The first is the development of imagination and the other 2 are drawings of observation. I decided to take take my game guide Pokemon Platinum, Pokémon, and add the third photo,Stage behind him. I used computer paper, colored pencils, colored pencil and black Sharpie markers

So yes, what do you think about this and how can we improve?
