Just needs a few touches probably. The forground and building look great. I had a play with the shot for 1/2 an hour...

^ Background probably suggests he's not a hermit but it was the first half decent shot of tunisia I foundon google images. Added a couple of bits of tech from Luke's house on the left. But even that's not really needed.

Matte paintings where used for a reason. To add scale and glamour to shots that couldn't be achieved (Or couldn't be paid for) any other way. God knows why Lucas insits on throwing away the whole practical shot and crating a new fake one.
