Yes, I prefer the modeled detail approach too. The problem with
textured detail, is that the closer the camera gets, the more fake
it looks.
The eye opener for me in this tutorial, was the way the most basic
geometric shapes could be altered with a few modeling tools. This was
why I had trouble getting started. I didn't understand how the tools
could get the shapes they did. This tutorial shows how, with an
interest subject to model. BTW, got the tailfin modeled, detailed, and
added.
