I think Adams referring to the ankle joints, in digitagrade legs the ankles are usually very pronounced and sharply visable, in reality this is due to all digitagrade animals being quadrapedal. People might be expecting that highly pronounced ankle to carry over into a bipedal being as well, but since such a creature doesnt exist in reality, you are of course free to do your own take on it and not be any more right or wrong than anyone else. I personally quite like it since it produces a very graceful arch from knee to foot.
Lucian, as for digitigrade bipeds, you are overlooking Dinosaurs, all of which are digitigrade and several of which are bipedal. For a living example, look at Ostriches.
Let me start by saying your art is amazing, sexy and inspired. I'm a big fan!
Oddly enough, there's far more relevant research concerning bipedal humanoids with digitigrade legs: Google the stilts people make for costumes and you'll find both functional systems and a great deal of analysis on the physics involved. Skeletal makeup is important for realistic art and these devices are a good projection of what could be. That said, suspension of disbelief is an important part of enjoying sexy saytrs. Cheers! #2c
The legs look kind of funny to me too, and I think it's because the ankle is too far up. (But then, there's no reason a satyr would necessarily have as long a lower leg as a human...)
That, and there's no heel.
Or also actually, it might be a balance issue, since her knees appear to be farther forward than her hooves but she's standing straight up (maybe even leaning forward slightly) from the knees up. So her center of gravity is way forward from her hooves.
