So it appears that he's sculpting Indy, but using Han Solo and Deckard as references. It's good that they try and get as many references as possible, but please Mat, see about a good profile pic - that's where some of the Fords in the past have been deficient.
just a note: For sculpting likenesses, I think we all tend to dig up whatever we can from wherever we can! Sometimes a film that was made near or around the same time as the film you're sculpting from works better, surprisingly! Blade Runner, for instance has great reference for Ford. lots of closeups, and moody lighting that show off his mug!
thought I'd offer that, not that you guys couldn't already put that together!
