My render engine was on the wrong setup. These are actually using the standard Liberty texture, including the exhaust. The only difference is that I upped the grey hue slightly so the blue parts of the texture looked more uniform with the rest.
someone asked for a side view, here it is.
As for details, I'd like someone to tell me what sort of details you'd like to see on the ship. Thank you for the feedback.
As to those who prefer the Atlantis as a carrier, allow me to say that most people I've met seems to rather dislike it, and after having seen it myself, the texture work on it is rather... mediocre at best.
Oh yes. Someone asked about the forward six tubes; they are no headlights, they are torpedo tubes. Of course, whether or not they will be weapons in game is doubtful, these are merely for the aesthetic of the design.
