According to Wikipedia, "The tengu...usually falls somewhere in between a large, monstrous bird and a wholly anthropomorphized being", and this appears to be the basis for Starscream's robot mode. While Optimus had a samurai helmet in robot mode, Starscream's helmet echoes his falcon form, a very nice added detail.
Starscream's arm cannons are replaced by flintlock rifles in this era, but he can also wield his alt mode's tail feathers as a bladed fan weapon. The cockpit chest of his modern incarnation has become a layered "robe" which looks downright elegant.
The ankles have a little forward-and-back articulation, but not a lot. His wrists are on ball joints, which makes them easier to pose with both weapons. And his wings can be folded in a variety of ways, depending on how you'd like to display him.
I feel like a lighter gray would suit the character better, and some silver highlights would make the blades look that much nastier. Maybe I'll touch him up later.
