In terms of color scheme, yes.
In terms of "somebody with a face that's scarred on one side", I would have to say that it looks a hell of a lot like Two-Face.
Assuming you haven't been reading Morrison's run, there's been quite a lot of red-and-black symbolism in what he's been doing with the Joker.
Other thoughts: the "J" on the Joker card is backwards and half its face is in light and half in shadow. (The light, incidentally, seems to be shining directly on Tim; that could mean something.)
There are three scratches on the giant penny (which is actually NOT associated with Two-Face in the the comics universe AFAIK), and Batwoman appears to be looking for clues of some sort.
The arm coming out from under the crate is in an impossible position for an intact body to be attached to it -- it's a right arm, so if there's a torso attached to it, it's cut off at the chest. Could be a dismembered corpse, could be a manequin or robot (the "Wayne Enterprises" stamp on the crate has to be significant), or it could just be a fuckup.
EDIT: reading through the
comments on Nrama; a lot of overlap between my thoughts and theirs. Something I didn't notice: there's a spoked wheel behind Hush. Could be from Babs's wheelchair.
