Other than adding some grey to the hair I'm not sure how they could have improved this fig. I have nearly 100 figs and this is in the top 5 in terms of extreme realism (sculpt/paint, cut/sew, body posability etc) In-hand it really is a shrunken-down Cushing.
One minor nit I noticed (other than sleeves needing to be a few mm longer to cover the white sleeves at the wrists) is that a few of the hands, most notably his "hand on chin" hand, have that line where they've inserted a new thumb sculpt to an existing hand, creating a very visible seam line. The HT Indy hands had this problem too.
Also, while everyone is constantly asking why so-and-so boots couldn't have been pleather, I'm the reverse - I'm not a fan of pleather boots (like on HT Han and Tarkin) and would rather have well sculpted/painted plastic boots (like HT did with red Skull.) The pleather boots never seem to wrinkle realsitically, they sometimes have scaling issues (too-thick foot sections due to material limitations) and they also have the danger of deterioration. That being said, these Tarkin boots are a big improvement over the HT Han boots in a number of ways, and I really quite liked the TFA Han pleather boots, which were a softer pleather that looked great.
