Big improvement, especially with the new wig.
It looks very nice...very Lust-y.
At this point I'll just be picking on details, you've managed to clean up the major issues. The pose is perfect, the whole, over the shoulder smirk is very Lust. I'm still not feeling the makeup though. It looks natural enough by itself, but against your normal skintone your face looks washed out and lost. If you can't go the route of lightening up everything that is showing, you should probably just try a more natural color that matches your everyday skintone.
A suggestion for your lipstick, if you're feeling adventurous, you could try re-shaping your lips in a "cupid's bow" shape for a more buxom pout. ( This is my personal opinion, since I love the old fashioned bombshell babes and the sexy lipstick. Yum!
This tutorial is a great basic instructional on lip lining and shaping. http://www.youtube.com/watch?v=6fNnehlYSlQ
One last thing, keep that gorgeous wig from tangling by using a spray like Motions on it and allowing it to dry. This way it'll always be beautiful and nicely kept for as long as you cosplay!
But like I said, it's all just little stuff at this point. ^^
I like what you've done so far, and the fact that you've made improvements is really impressive.
