I really can't find anything to complain about on this piece. I'm a fan of the character and I really like your take on her. I noticed the red bandana symbolizes her cape as far as colors are concerned. The chain breaking tattoo is dope. I love her tan skin tone because it shows that she spends a lot of time in the sun. It's where she gets her powers from anyway, and I just can't wrap my head around why some artists always draw her pale/pinkish in skin tone. Drives me nuts. And finally, I love the thickness of her curves. Not only is it a throwback to the curvier models of the 50's, but it makes perfect sense that a hero as strong as her would have some meat on her bones. Not just extra large breasts on a twig body. Superman is never drawn like a stick with an overly large bulge in his draws, right? Same should go for her.
My only minor gripe is that her thighs are big, but the booty is a little thin. I understand how she looks like she squeezed into the shorts, but the lack of booty doesn't compute well with me.
Overall, very nice pic. Also, add some things in the background next time. Make it look like she ended a car chase by ripping the engine clean out of the getaway vehicle. I dunno, just be creative.
