Thank you, Eliot. Very kind words, and wonderful suggestions.
My replies to your numbered comments:
1. In regard to traction motors, cables, and air intakes, Id be happy to add them, but im not sure what/where they are located? Here's a (cr@py) photo. Are these the things you're suggesting to build? Also, where are the air intakes that you mention? If you could point them out on a picture for me, that would help me greatly.

2 & 3. Good points, all. I'm going to see how those areas look when they're textured. Sometimes textures can hide the faceting, but if they still look a little rough, I'll smooth them out as you suggest by adding a subdivision modifier, etc. And as far as the nose is concerned, I have a feeling that Im going to be altering those surfaces quite a bit to get the converging textures to all work together, but I will definitely keep an eye on the smoothing of it, as you rightly noted. :-) It has always been a tricky area for me to do right. Even with MSTS models way back when.
Thank you again for your suggestions and compliments, Eliot. They are greatly appreciated. If anything else comes to mind, ideas, opinions, suggestions, ...feel free to pm me. Full speed ahead!
