Sweet. I dig the colors. They remind me of the old UPS web site and one other I won't mention.
Narf is right that the fighters look awfully skinny. This is not a problem, but I must wonder if it will look bad once the images are shrank for the mini-pics.
I cannot tell if the Fighter's tail is asymmetrical or if the other half of the tail is viewed edge-on.
Similarly, the Cruiser may be asymmetrical or it may be that the effect is simply a result of the perspective. Perhaps a wider angle lens, a slightly different angle of view, or more pronounced asymmetry will clear that up.
Great looking ships. I do like their lines.
