Some refinements on your Vasudan fighter:
1 ) Make the wing segments become somewhat thinner once they extend out beyond the main body.
2 ) Alter the sweep of the trailing edge of the wing, so it doesn't come to a point at the tip.
3 ) I can't see whether you've done this on this model, since the ventral isn't visible. I see that you've recessed the ventral sections of the engines (a nice touch BTW) both at the rear and sides. I'd advise you to have the engine structure on the ventral engines extend more forward on the hull than on the dorsal, so they can become missile bays on their front end, perhaps with a bit of sweep to match the wing leading edge.
Since this craft looks a little more solid than the Serapis, perhaps this could be a new all-Vasudan space supperiority or light bomber, kinda like the Athena in that its almost part-fighter, though I see it having some stealth characteristics. Whether this is Loki-type stealth or Pegasus-type stealth is open to debate, but I think that the textures chosen should reflect this in either case.
Later!
