This is quite an intriguing design, and I think I like it for the very weirdness that stops me from saying flat out that I
do like it!
I can see how Star Dragon thinks it Klingon-ish from the rear as the "saucer" (or would that be 'head' instead?) looks like it was inspired by Vor'cha elements. I don't know of the SAAB Hammerhead fighter, but I automatically assumed he was referring to the hammerhead shark.
I agree that the textures are a little weird but I didn't realise that they were scanned, hand-drawn designs. That is seriously awesome. As for making new textures... I think this would really good in a Sovereign-era colour scheme.
She looks really good in the first pic, from above the bow quarter. Keep these coming, they are really cool ships!
