I've seen a pic of Terrorsaur, looks pretty good for an Airrazor retool
Pteranadon mode looks good to me, with the concession that like most TFs with jet/aerial modes it looks best from the top.
He looks decent in botmode, a bit sleek maybe, and the wings on the back are quite off model but will probably not be an issue when you have the figure in hand.
It looks like he has a faux chest piece made to look like the back of the Pteranadon so they didn't have to reorient the transformation scheme.
I'd say on the whole it's the Botmode that's compromised (and only barely) which was the right choice as Terrorsaur's onscreen transformation involved CGI magic...
Can't tell size from the images I've seen, but a pretty significant re-tool.
From what I can tell the major shared parts are the lower legs the forearms and potentially some of the internal skeleton/structure.
Head(s), wings, chest, waist, feet etc all look to have new sculpting
To be honest he's not really show or toy accurate, but you can tell the team at Hasbro have done their best within the retool budget allowed.
Pteranadon head (articulated opening mouth) on the back in botmode, and what looks like a faux chest that remains the chest in Pteranadon mode.
Wings are tip down (not upside down like the OG toy).
