Keep at it. It is a lot of work, never will you be done learning once you go down this path.

Are you using Blender? If so talk to @theanubisrider he is my son, and handles most of my 3D Work and is quite skilled at Blender.

I can LOOK at code and give you feedback, but I don't want to criticize anyone's 3D work when they are just starting as it is a tough road, and is pretty cool if you get the feel for it.
