I think it looks okay. I think it would be nice if you make it bigger next time. I think his pose is good. I think some shading would be nice too. I think the detail in this drawing is good, I think details will not be a problem in your next drawing. I think it will be good to make it in a blank white piece of paper next time too, with out lines because those lines go through the picture. Anyway, other than that it looks good.

The shading's okay, but Kid Thunder there could use a footstool.
