I BROKE HER INTO PIECES and then I fixed her leg.
I'm not at all fond of the gun but I'm too lazy to edit it, plus mtr has already worked his magic with that, so look at that.
If you want her legs to be straight, you really ought to make her balanced for real.
Which I attempted with this edit. Tell me if I succeeded!
Ouch, it's ugly. I simply tried to make her legs correspond with the pose of her upper body. It's not very dynamic, as you can see, which led my leg edit to be very undynamic as well.
Oh dangit, I hope it helps anyway. ): This is by far my worst edit for a long time.
