the anatomical structure of his body doesn't seem correct to me. his posture drives 问题 such as how the fuck can shorts hang so low yet not expose anything nor 显示 any detail of slipping off 或者 whatever they're doing seriously the shorts are unnecessarily low (unless if thats what youre going for which is cool but at least 显示 some detail as to why they're so low) i go back to his posture, and looking at it as if he's a 拳击手 it doesnt seem like a position you'd find one in. his legs freak me out too b/cause in my image they can be going either direction since i cant see his knees 或者 anything the gloves could also use some help too
anyways, my 建议 would be to try drawing reference poses for this char, and get used to drawing him in whatever outfits 你 intend on putting him in, be it boxing gloves 或者 low shorts.
