How to improve this human model?

Hi!, i´ve make this model using references from, and i would like some help to improve the looks of the model and maybe even the topology, trying to get as little polys as posible, thanks in advance and sorry my english.

looks good… i think… the only thing I can see is the sharp poly (vertex) left and right near to the belly button. For deformation you need some more edgeloops on the upper and lower leg and try to avoid that triangles. Place them somewhere else.
