That's delicious. I'd say the cockpit design is very good now. I'd still like to see the two lights on either side of the glass incorporated somehow though.
The secondary bay above the cockpit looks tacky. For sure have them point forward instead of up, and maybe something to make them look less like eyes.
The side missile bays look great. Maybe down the road, consider making them dirtier with scorch marks and such.
Consider modeling in those lights that are found on the current HTL boa. Or, you could choose not to, since they're easily doable with normal maps and glow maps only.
Rear thrusters: Could you fool around with the greebles a bit, so it doesn't look like 3 dishes stuck on a plate of metal? I realize that the part is going to be partially obscured by the thruster plumes (but still quite visible, since the next mediavps feature significantly smaller thruster plumes), but something as simple as deepening the hollows and a few simple pipe greebles might be all that's needed. I'm not positive this small cosmetic change is worth the effort, so I'll just offer it as something to think about.
