Mmmm she is very sexy! I like the pose you chose must've been a challenge with the angle of it and perspective. Also dig the shading and soft tones on this, might I ask what you use to lend? Do you use SAI or PS?
This is a nice sexy pin-up piece. I think you hit the mark you wanted, which was to show the viewer the panda's sex appeal. Her outfit/armor is also very nicely designed.
I would suggest that if you want to do something more natural, please use a reference for the body placement/pose. There are a few things that don't look natural (her limbs in general seem curved, her right hand is odd, and her hair & bottom aren't following the laws of gravity.. maybe she just has good hairspray like most anime guys and gals ^_^).. but then again, I don't think people are looking at any of these things when they see her.
Over all, it is cute, and her body language is spot-on, I'm just giving some areas that you could improve on.
NP ^^ I was thinking, you'd do excellent in a figure drawing class. I'm not sure what your age is (not asking) but if you can, find one at your local college (community college's offer them at lower prices) or art museum. You clearly have the talent, you just need some studying to catapult your skills.
