Some really nice ones there.

If I may be critical, picture number 4 looks just a bit too busy – your eye doesn’t fall anywhere and it’s a bit too jumbled – for my tastes.

The B17 & crew shots look too tidy, on the other hand, to appear as realistic as you might be trying to imply with your b&w shot. It’s the expertly manicured lawn and dressed propellers that take away any drama, I feel.

The Dragon Headed Yak also, doesn’t quite work. I think I can see what you were trying to achieve – but unfortunately it just comes across as an accident that happened.

Still, very nice all the same.
