Those are very good results for only 2 weeks; Just learn skinning and you are well on your wayto making some topquality models.
As Silver said, pay no attention to any negative comments, unless they accually have something constructive to say. Those than can,Do; Those that can't, just whine about others work to make themselves feel better. I say there is no relavance if the models are basic shapes, as long as it looks good then it works. I have an enemy model I put up here made (almost) entirely out of the basic shapes provided by Milkshape. It's called "grizzly". Keep up the good work.
JEEZ!You people just STFU! You waste more space complaining about people wasting space than the people your bashing! Man, I thought I had no life.
