Cool stuff man, unique style of people looks cool, but my only suggestion is you need to some more say studies or something of anatomy. Life drawing classes are great, do you go to any?. I think you need more variation in body sizes and positions and stuff... life drawing helps immensly, especially when u get the fatties and oldies.. tonnes of varition. Same applies to like faces etc. Looks good though.
This is excellent the face and anatomy isnt really excentric so works well. reminds me of Matt Rhodes' work , top notch.
