Beautiful work so far! I can't help but notice though that the laser cannons' flashback suppressors are 90 degrees vertical when the wings are open, when they should be perpendicular to the wing surface. Also, the cannon bodies are rotated away from the orientation of the wings when the boxy greeble on the outside should be parallel with the wings. Are you going to address this in the final model?
For reference, in this image red is your cannons' orientation, green is how they are on the studio model:
