Good job, Sni- Rah Tor'h...

However, I feel like being picky.

There is no depth perspective that I can see. Look at the Orion or the container in the clutches of that Triton on the left. The geometric shape should grow smaller as it gets further away from the camers; instead, that Orion looks like it has a huge rear.
I second all the shadow remarks - you'd be amazed at how much a picture can be improved by having true shadows and light sources. It's simply a matter of the natural appearance that our eyes expect to see.
Last thing: Good job at breaking out of the dreaded 2D ship arrangement. However, the pic
is a bit cluttered. I would take out one of the planets, since having two bodies of that size next to each other like that just doesn't make sense. Also, move the Sobek somewhere more visible - I had to hunt for it.

And the main thing: depth blur. The pic as it is now make it very hard to tell the scale of things. If you added an increasing blur to an object the further it got from the camera, it would help immensely.
