http://www.hard-light.net/wiki/images/Mekhet.jpgwhile I can see the similarity with the forward protrusions, that is it. I have to agree with Hades that in it's current for it dosn't look Vasudan.
Normally I am a fan of your designs but as a suggestion the back edge of the upper armour plates want making more ovoid than right angle, although separate armour hulls is new to Vasudan designs the tail section of the Sobek has fins which coulp provide a good template.
It might also be worth making the forward section of the main hull come to a rounded point, or perhaps do a Typhon/Sobek nose would be a better idea.
Also the main hull has two large expanses of flat hull, the bottom and a slight smaller area on the top. Vasudan craft normally only have large expanses of flat on the bottom, the top is usually a curve all over, see Mentu, Aten, Isis, Thoth, Tauret, Seth.
By and large though the concept is intriguing and I look forward to seeing how you develop it.
