This plane is looking really good now, did you visit the Paint Simmers website for help?
I am afraid that I don't know much about compositing other than what it is, I think there are some tutorials on it that come with Maya - I'll have a look.
Are you going to put insignia on this plane BTW?
Tickety boo and ta ta for a bit...
