Toph sketches

I really love the Avatar - The last airbender series. The story is ok, but its style is that i have gotten really into. The different cultures of each nation, their clothes, buildings etc. And since it isnt a real anime, the whole appearance is quiet unique - in my opinion.
So of course i got the feeling that i wanna draw thing like this. I looked up some screenshots and finally i ended up with drawing Toph, the blind earth bender. She is one of the main characters (or something like that xD).
I printed some pictures from the episode when she first appears (The Blind Bandit, Chapter 6, Book 2) and used as a ref.
I made some sketches in my really small sketchbook, added some light colors and decided to upload it here.

The two colored sketches are ok, i think, but the little uncolored one is horrible. Never mind.
The bg is some kind of... yellow or greyish... thing, but if i had added more light to it under scanning, the little one in the left corner would have disappeared. And i didnt feel like paint it white digitally... Sorry.
And the colors are light, cuz i have really bad colored pencils and i didnt dare to color it harder.

I used a pencils, i think it was HB, but i'm not sure, and colored pencils that i found in my drawer.
