Catwoman

Great spotlight circle frme!  Maybe it's the full moon, but regardless it has lots of nice geometric curves and circles within it that stick out.  Partially the Batman the Animated Series look that counts on the simple and elegant lineweights. 

Dynamite!

that's an interesting canvas for a blank cover sketch, with the (intentional?) tearing and discoloration of the background giving it an old age feel even though it's modern printing methods. That makes this more old school Cat Woman image feel appropriate stylistically.
