This model is already and going to just keep getting better and better. U said that the upper body only took u one night in ur spare time? I barely get my image planes set up in one night.
Q: Did u extrude the edges around the neck of the head down and just kept on extruding to model the upper body?
U should start a portfolio or something maybe with some walkthroughs of your work and maybe some tutorials.
I think i speak for everyone on this site when i say that ur work is dam good.
