I love this 'A Little Sad Keanu Reeves https://www.shapeways.com/model/364717/?ca=email&ct=0920& amp;cr=01 I would love to be able to make figures like this of my friends to sell and give as gifts. How to begin?
Sculptris is for sculpting models. Shapeways is for printing them. There are creators available such as the ShapeMe that you could use on Shapeways that all you need to do is upload pictures.
Sad Keanu was created by Blender, which is a free and open source 3D modeling software. There's a good tutorial here: http://cgcookie.com/blender/series/creating-a-realistic-head / ... or you can post on the "Need a Modeler" forum.
Life drawing classes are a good place to start if you want to do figure work -- and what could be simpler than pencil and paper.....
Try this one: https://www.shapeways.com/tutorials/shapeme Make sure you use good pictures in neutral lighting!!! Otherwise the print comes out sunburnt. Check out the examples.
