Hey!I see you like 3D!I'm very good in 3D modeling.It's pretty much what I want to have as a job.I'd love to see what program you're using.I use 3D canvas,Anim8or,and Sketchup.Mainly Anim8or.Since you are adding the materials sepperately,I think they could be a bit worked on.Their is some places where it loooks a bit squiglly and fuzzy too.Some of the models could be improves as well.I suggest you find a way to add the materials onto the model it self and then use a rendering system like Kerkythea or Pov-Ray to enchance and better your model.I find renderers can sometimes even make it realistic.It would smooth your models out greatly.Keep up the great work!
