Goblin Chemist (WIP)

Oh well, I'll try improving my drawing, so here is a concept I decided to draw, I plan to color it, but first I would like to know if there is something to fix or to make again.

He looks more like a midget then a goblin, draw the body first then add the cloak.

He needs to see someone about his feet.. i cant imagine how many times he trips.

The angle of his legs suggests he is either squatting or deformed.
