Thank you very much my friends!
And excuse me for not replying comments and post images more often, as I should... (my internet connection is still damn slow and I'm still lookong for an alternative to Photobucket)
Indeed with the new mannequins it's much easier to achieve dynamic poses and well proportioned bodies!
Of course it takes some extra previous work to prepare and re-cast such mannequins, but not so much more compared to making a metal wire skeleton... and then, with some body parts voumes, and a basic anathomy already on the mannequin, the sculpting becomes quicker and easier!
And after so many figures my sculpting also improved... I still have to learn better and act practice on some features, but I really enjoy to make particular tricky things like different expressions and faces!
