Cool sketches. I cannot wait to see them as models. I usually model in polys. I model as if I were using nurbs patchs and then I merge the verts. Polies are so much easier to work. I saw a new function in 5.0, if I get it to work. You can convert the polies to subD's and then the SubD's to Nurbs. That would be sweet to model and texture with the ease of pollies and then animate with the cleanes of nurbs. Have not tried it though.
