trying to get into character design, I've got decent knowledge of 3d max, and basic knowledge of z brush, anyway here is my work so far created using zspheres:

test 1.jpg

1. anyone know any good tutorials on how to draw hands, feet, and face shape?

2. I know I'm working with millions of polygons with this drawing but I want to be able to animate it in 3d max. Is there anyway of optimizing the drawing to have all the details but to have lower poly's?

3. Any good tutorials on uvmapping and creating clothing for a character?

4. tell me what i'm doing wrong so far, and what's right! i have alot to learn about anatomy and i'm reading books these days lol

Thanks for any help you guys can give me in advance! this stuff is hard but i will get to you guys stage eventually!
