More or less, like that. I search on google for Romulan Warbird and you'll see the similarity. Still, I'm seeing a bird like design. Heavy Cruser to Warship class based on the mainly forward directed weapons (three prime weapons appearing to be non-adjustable in a delta formation).
I'd expect this kind of ship to have a squadrun of about 3 or 5 Frigates covering it's rear and providing cover fire.
...or you know, I can make more sense saying; blah, blah bla-blah blah. ^_^'
I like it! I've been trying somewhat to design ships myself, but all my designs keep looking boxy and awkward. This design is very sleek, and I think it looks very original. Also you did a superb job on the coloring.
