Photo Diorama

[Spitfire]

I like the "turbulent" water, it looks good to me. Since you don't have the diorama handy, this is more of a theoretical suggestion, but maybe if you were to actually accentuate the turbulence a little, adding some tiny "whitecaps" here and there. I have found that in model railroading, as in life, the key is making the "mistakes" look deliberate!
