Cool stuff man.. sory for replying late
I think the abs are too huge compared to the body.. something like 20 to 25% smaller will work. The strap going around the chest could have some more detail.. like maybe some more pouches.. more grenades.. accessories it more to make it look more interesting.. something like a knife, a transmittor etc. The device on his back is not working with the concept.. some thing more interesting will do.. but what we see right now doesnt really works well and feels flat .
Overall nice proportions, nice face.. Keep it going and make him a bad ass
