Thank you guys!
Domingos : well, i hope i'll be able to make a cool model. I think that i'm going to model it as a a big puzzle..each part alone (faces, legs, arms, mouths, eyes, etc...) and make them one piece at the end.
gpepper : Thank you! i'm going to thicken up as much as i can and we'll see

... i have to make a low poly and ask to Moddler what they think about it.
andrei.szasz : thank you! even with bigger legs i'll do my best!!!
today, i'm going to draw the masks, in order to see how many pieces i'll need for each part... i think that if i sculpt differents mouthes, eyes, noses, i'll have a large catalog of expressions...than i'll tweak them one by one in ZB to make each mask unique...
i cross my fingers
again thanks for your suport
