The Cheshire Cat: Thanks you!
Jaidek: Is not completely sculpt in zbrush imported from Max a very basic model.
kyphur: Thanks a lot!
stalsby: Thanks! Was a good anatomy practice.
Agent00J: Thanks! I really like wrinkles on the clothing, I think gives a mode natural looking
ricardo_sousa11: Thank you man! I really appreciate it!
jaystein: Thanks, I decided to do superman because of that as well.
Kupo: thanks you mate!
zerodean: Thanks for the comments! you are right I didn’t use any reference for the wrinkles or the stretching I made it just like I would like to see it, so I’m sure are not real at all. About the form along his spine I know it should more flat, I agree! I just though looks cool that way. Thanks for the help 
comic_craig: Thanks, I like the model better than the render as well.
Thanks everyone!!!
