very nice, a good clean start
if i may be so bold a few pointers.
The bicep is a little oversized compared to the tricep, which is infact the larger of the two muscles. With an elbow in place the lower arm might look a little disjointed
I dont think that the legs are too short, more that the diaphram is too low and wide and the belt is also slung a little low, raising the belt and adding a little to the outer thigh area migh help sort that out without having to amputate the legs, the knee seems to be in the right place
finally the small of the back/arse area could do with a little tweaking. If you could bring the base of the spine in about 1-2mm and add a little to the arse it would gice a more dynamic line to the figure
please dont take these comments as negative, you are obviously talented and I know how hard it can be to develop technique without the odd critique
