He looks better with the ajustment you’ve made…
I think it all depends on what kind of character he is going to be…a worker, or chair jockey…If a chair jockey, then he is just right now…if a worker, than maybe get some outside curves going on in those muscles…like the deltoids/shoulder muscles, thicker wrist, forarms, lowere leg/calf muscles ect…It’s the accentuation of those opposing curves in, and seperating the different muscle groups that will give him rhythm and life…You might just for the sake of experimenting, make a version #2, while saving this version as #1…and on #2, try out the inflate and clay tubes brushes to get those muscle groups more defined so that they create those exterior and interior oppossing curves…Just a couple of suggestions that may or may not be useful to you, but thought them worth mentioning , just in case they may be…
Keep pushing him further…
