Yeah i like that green demon piece to. Only thing i would work on is the rocks. They seem a little composed - making room for the characters and going out of the frame almost at the same hight on each side. Twist them a bit and make a piece of rock stick up in the foreground. Nice anatomy studies, the dude is nice - the female looks like she could beat the crab out of him tho. I thinks there is a drawing of bodystrukture in mentlers thread - kinda of a 1,2,3 proportion drawing (i use it as wallpaper). I tend to make my females look a bit too strong myself btw. Keep up the good work dude!
