This is probably your sexiest picture yet! It mostly works because it doesn't focus so much on butts this time. In fact, it doesn't seem to have much of a butt in it at all! I'm so glad you instead chose to focus on this beautiful woman's breasts. Emma Frost is one of the hottest Marvel characters ever. An artist as good as you deserves to pay tribute to this vixen.
I didn't even notice her erect nipples at first. I think there's a camel toe as well. It just goes to show how much you can show without explicitly showing private parts. She really has a sweet hourglass figure. The leg muscles look strong too. It's the perfect appearance of a hot woman!
