I haven't read the Honourverse, but man do those pictures look cool.
The first one has that feeling of an 18th century battleship firing all its guns at once, except on a cool futiristic spaceship. And the second picture reminds me of Homeworld for some reason.
Great models, great lighting and composition.
My only complaint is that the second picture is a bit sparse. More than that, it doesn't have a sense of balance. the left side is a bit empty. What I suggest you do is either fill it up wioth some spaceships or planets (a partial view of a planet right up close to the screen on the left edge would be cool), or rotate/zoom the camera to get a better view of the missle salvo, its a bit distant. That, and perhaps make the laser shots coming out of the turrets in the first pic a bit more out of sync. Its look kind of wierd, having them all in the same stage of firing. Perhaps shorten/elongate some of the beams, and make some a bit away from the ship to show that they have been fired right before the picture was taken.
I know that sounds like a lot of complaints, but its not. For the most part, both pictures are great.
