Very nice. Coupla tips - the access panel doors near the rear on the booms exist only on the left side of the booms (that's on the outside of the left boom and the inside of the right boom).
Also, go into the game, get in the skin, sit on the runway and go to external view. Now make sure all the control surface panel lines correspond to the actual control surface when its moved - I think I recall many panel line errors there. Be sure to do top and bottom of all control surfaces.
Good start, and welcome to skinning!
