Great work so far! Take a closer look at the kneecaps though, they usually aren't a very solid form because there are several separate bones that make up the structure beneath them so it doesn't look uniform or symmetrical like yours. I'm no anatomy expert but that part did look a little off to me. Overall, awesome though!…
Looking good, but some things are abit wonky, mostly due to a lack of definition. You've really defined your upper torso and arms, but everything else is a bit lacking, and some places just didn't seem to get any attention at all (the legs, in particular the back of them). The deltoids seem a bit small/underdone especially…
