Find the Clues on the Battle for the Cowl Promo!

Apparently, there are clues to be found on this Tony Daniel promo piece for Battle for the Cowl.

Now, in the past, some of the clues on these promo pieces did not exactly, you know, pan out. But since the guy writing Battle for the Cowl is the same guy doing the promo, I bet the odds are these clues will.

So any guesses as to what the "clues" are in this piece?
