Cool space effect. However, overall, the image is lacking in a clear subject. It might be better with more lighting on the ships, and if they were close.
I like the look of whatever this is... This would have done well in the puzzle macro challenge. I like the use of the colors and the interesting pattern that the smoke (I think that is what it is) makes. Good composition.
I think the 'rays' are a bit much, how they go up and down and that red spot and bright areas are just really distracting. May have been a stronger image if it was cleaner.
