First off, love the total picture. I've always loved Catwoman and Her various costumes...and this one is no exception.
The slight curve in the ears is rather interesting...lots of time, they look like they're just a straight line/trinagle shape. The fingernails are not that protrusive; just long enough to show that they are there...VERY nice touch! The way you have the 'shiny tones/ on the suit show a great deal of attention to the lighting here...not just "There, it's lit to the left" kinda stuff. The belt is riding the hips just right...not a bit lopsided. ( I mentioned this in another posting somewhere here at HM... ) The way the zipper goes all the way to the neck is congruent with the overall 'fetish-look' that all of the 'Catwoman Suits' have had in the past.
My only problem is the whip. I understand the "cat's fang" at the end of it...but, why does the whip look like it's made up of several parts? Only thing I can think of is that it's done that way in homage to the suit Michelle Pfeiffer made in "Batman Returns"...the one made out of several raincoats, if memory serves me. Other than that, a bulwhip is one long braided piece of leather...I'm more in the 'cat-'o-nine-tails' myself.
All this needs now is for one of the color masters here at HM to work their brand of 'magik' on it. I'm also giving it a 'ten'...you've earned it.
Nice job here...hope to see more work like this from you
