The sculpt itself is absolutely fantastic, but the subtleties intrinsic to boxing fall a little short.
For starters, the shorts are far too low. They should be above the naval and most of the lower split abdominal.
Second, boxing shorts fit much looser than what is sculpted which wouldn’t be a big deal normally, but for a guy with body fat around 7%, there is no way that he should have flesh overhanging them. Perhaps on his right side with the compression, but not on his left front quarter.
Third is the pose. I cannot quite decipher what he is doing. He looks like he is attempting to block an attack or something? It could be the viewing angles, but his weight doesn’t seem to be sufficiently on his rear foot. Its the anchor while all power comes from the torso - regardless of being offensive or defensive. If he’s doing a left hook, he’s about to lose balance and most likely fall over. If this is his neutral stance, he’s going to have some broke ribs at the end of the match.
Lastly, It just struck me that he’s not wearing shoes, so he’s not a boxer… but hes wearing boxing shorts. Unless they aren’t boxing shorts, but they don’t really look like a typical pair of mma shorts.
So yeah, boxer, mma, kickboxer, it all still applies. I’d love to see your pose reference if possible!
Anyway, outstanding sculpt! Just some nitpicky snobbery coming from a guy who grew up boxing and watching ufc.
