As useless as I know this statement to be, I kind of have to say it... it doesn't really look Vasudan. That said, there's a lot of diversity to Vasudan designs, and textures wil make a lot of difference, so therr's still that, I guess.
For more specific suggestions, I'd say that the most jarring part is the head. That flat nose, and those flares at the back have no precedent in vasudan ships as far as I can recall. I'd suggest replacing it with a more bullet shaped head, like the sobek, or even a more interesting, pointier head like the Typhon if you're feeling adventurous.
Also, while a lot of Vasudan ships are very smooth, there's room for some greebling - at present, you have an interesting shape, but quite a plain, underdetailed model. Detail work for Vasudans is hard, but it's done very well on all the mediaVP Zod HTLs (Hat, Aten and Typhon) - look to them for ideas.
