I still think that the vertical tail looks too fat! Just make a small thin light effect. Hard for me to tell you in english. Maybe check my Ju88 threat to see what I mean. http://www.simmerspaintshop.com/foru...-ju-88-d-3174/
Generally I think your wing undersides are too light, but each of us here has another taste. I like it much more darker.
