What are you using to model in?
I played around with 3-d rendering just a little and it would have taken me 2 years longer to draw it then to just freaking build it. Awesome work both in the drawings and in the craftsmanship.
If you don't mind me asking. About how much do you have tied up dollar wise so far? I have a stumps clone in my future, just not sure how future its gonna be.
