You just show all of your talents now… Great pose. I do have something, though. This pose is kind of a “panic run”. Meaning, it´s almost like someone has just thrown a grenade behind him, and he´s trying to escape it. And I think you´re looking for a more joyfull running style here. To get that, I think he needs to bend less in his spine, removing this “almost-running-away-from-his-head” feeling, which is a little cartoonish. This is just a test, I know, so I´ll follow your progress, and get back to you.
Actually never posed a character in 3d, only modelled static views. Even thoug I´ve been in 3d for many years, I have only really tried to understand and learn this field for the past 3 months, starting by joining this challenge. Drawing is still my main approach to the creative area.
It seems like you have skills in all 3d areas, only thing I don´t know, do you make character animation as well?
