the problem (in my little opinion) is that the basic theme of your art does'nt jump out.
I mean the subject is a crashed hellcat right? Now there's a hellcat alright, and it's down, but it's behind way to mutch smoke. Move the smoke out of the way, show us the guts of a smashed up confed hellcat (lots of pipes or conduits, generators and wires, twisted frame-work).
and you could reposition it to the very front/bottom part of the screen- the waves are nice and all, but nobody gives a flying f.... about them. that last part was harsh, I apologise
