I put these comps together of Deckard and Han. To me it seems like they took the TFA sculpt, got rid of the neck, modified the hair, added new ears, and gave it stubble. There's too many lines that match up just so and the expression seems the same.
I haven't paid enough attention to the K sculpt but it does remind me of the BBK Toys drive figure -- I'm not hip on all these third party companies so maybe it's the same people. Anyhow my thinking is just that if perhaps they follow the same approach I'd be very curious to know what young Ford they'd use -- not many good options to be honest.
