Made in Blender. Still lacks some actual texture painting for details and needs to be rigged for poses. But all in all I'm already happy with the result.
Another render. Changes: little details here and there. Most importantly: I added a rig to the modell so that I can have it in poses and even animate it. During the process I realized, that I'm not so happy with how the hands turned out to be. They were way to big and some other problems occured. Else I think I'm pretty happy with this stage and not sure I'f I'll add or change anything.
