I just try to make myself happy. Which is hard to do sometimes. I try and acheive the most realistic results I can possibly do every time. That doesn't always mean that's what the results are. I believe Clay Kemp once said, and please don't hate me if I'm wrong about who said this, but I think it was Clay; try and look at every piece of the model as a model in itself. And make evey part look as good as you can and your level of detail will just get better and better. I think this is probably the most sound advice I've heard. Do this, and in time; you'll be happy with the results. Unless you're building it for somebody else, just build it the way YOU would want it. And don't listen to Junkpile, he lives in Kansas! LOL, just kiddn! I live in Kansas too.
