Is that a lunar light projection, or a sunrise? anyways, the rock texturing is quite fantastic. The light/glare effect on the rocks on the bottom right is well done. As for the ship: I would have created a red flare light effect on the water below it (somewhere centered on the body of water). Or perhaps some red light on the tips of those bottom/right rocks. Unless you intended that the light source on the horizon was lowering contrast of the explosion's light effect on the piece. Beautiful work really!
