Very nice! I am looking into shooting aircraft myself, as an extra means of revenue. I am presently a member of ISAP (Intl. Society for Aviation Photography) hoping to get a little help with getting a foot in the door.
If I might I suggest one small thing, have the broker arrange for an authorized FBO agent to power up the lights on the plane for the shot. Other than that, your skillful use of the SB's is well illustrated.
