I like the new versions. You work pretty quickly. I'm not sure how much further you will be able to get without studying anatomy properly. You've got pretty far which is impressive, but I'm still seeing a number of tweaks that need to be made. Some of them for example are:
- nipples too high
- abdominal region too flat (should be more cylindrical)
- tricepts too small compared with deltoids
- front view his right arm switches muscle overlaps just below the elbow
- side view left shoulder too far back and no form defined for the spine (a lumpy mass covers right over it)
I guess there are more, but I could keep suggesting tweaks forever until you refine it as good as my knowledge (which is far from perfect).
The important thing for your development as an artist seeing your passion for drawing beasty characters will be to keep studying the human anatomy. Then you yourself will know the parts that need to be tweaked - or better, will be able to draw it correctly from the start. I recommend working through the anatomy lessons at
