Suggestion: Turn on anti aliasing and save your image as a png for better quality. As it is now it feels too dark for me to get anything out of it. It also looks too "clean". You are using 1024 textures correct? It just doesn't look like it's detailed enough. I'm not a skin expert, just my opinion.
I'm curious (never done a B-24 before), but there's this white line/stripe on top of all the engines. Is that the way the real plane was, or some glitch in the skin?
Looks good! I'll be glad to fly it, since I flew in the real one
