First, thank you all for the nice comments!
Well, the the rendering time for the smoothed is about 20-30 sec... So it's not that time consuming! As for the base mesh, there is 7k with faces, attaching some wire images!
Everything will be done in maya except for the animation wich will be done in Motionbuilder, just because they show the everything in realtime!
I'm currently working on weighting the head...

Take care everyone!
