No matter. I like the attension to detail with the texturing. Like the burn marks from the afterburners on the catapult. You could improve the lighting if you wanted though. Maybe add it in water and using a color and reflect map to add wake with foam from the sea? Maybe play with sky images placed on an plane that is only visible in the reflections for the water to also reflect? It is like an HDRI fake. Have you every played with rendering it with Mental Ray? You could add some nice soft lighting with FG and GI? another thing that adds to the feel of size is using a camera with a strong perspective or destortion from a wide angle lens. The lower the number of MM the lens is the higher the perspective it adds.
