The music sounds great!
I think the clip works fine without the orbital shot of Tatooine. It is R2 and 3PO out in the desert. Where else would it be other than Tatooine? If you wanted to announce it is Tatooine through the music instead of a visual, you could drop in a very small segment of music from the original Star Wars score from when the droids were wandering in the Jundland Wastes.
