Well, my only experience with 3d art is with a program called Wings3d. I can't say much about it. If you know what you're doing (And have got a comp that doesn't get a heartattack at 20000 poly's

) you can create some nice things with it that I would call art. Me, I am just messing around with it when I need to get rid of my creativity or my head will pop.
For some stupid reason, the only thing I am somewhat decent at is the modelling of sci-fi spaceships, most of them original stuff. Remaking a Constitution class or something like that is not my cup of tea. Everything that isn't a spaceship just won't work.

Maybe I should imagine a person to be a spaceship with the head being the front.
