Superb work. I really like the engine greebling. The pressure vessels are a really nice touch as is your tubes that go from the engine to the fuselage.

The initial texturing also looks to be going great.

I like the lighting you use on the black and white renders. Some kind of occlusion mapping thing? I'd like to experiment with a couple renders like that with the version I am working on.

I am looking forward to your fully textured final.
