About selling models...
One big thing is materials, very detailed and clear model will look very crappy with crappy materials.
I don't know anything about selling models but I think that if you are a newbie, you should buy materials also.
It's very difficult to make realistic materials (well maybe not for everyone) ie. that rubber material in that wheel took me many hours to get sorted out.
