Stjepan Sejic draws some beautiful women and excels at dark fantasy characters and themes, which is why he has done such killer work for Top Cow over the last couple years. That might also be why I think he renders such an amazing Wonder Woman. She's muscular and powerful without losing her beauty or femininity. Most importantly, she looks like she doesn't need a battle axe or sword to win a war.
His Black Canary is interesting in this image in that I'm not sure I've ever seen her wear a top exactly like that. It looks a little like her Brightest Day with her bulkier leather jacket replaced by a form-fitting biker jacket with fastens instead of zipper. Either way, I like it, particularly the shiny buckle or button at her throat, which reminds me of the canary that used to adorn her choker in the Golden Age stories.
