I have to admit I really love this piece. The expression in her face is really good, the waves in her hair are pretty, I love what she's wearing. A very cute costume as well. I find it really cute that she has nothing covering her rear too. I have the feeling she's looking for a good time.
I also really like the pose. Her left leg can really stretch, wow.
No, overall it's really good, she has the cutest face, and it would be the perfect temptation to get a guy if that was her intent.
I'm not ashamed to admit that I'm a fan of fluffy tails and the derrieres they're attached to. This pose showcases both beautifully. Not overtly, but hey, if we can have side-boob, we can have side-butt as well! XD
In all seriousness though, what seem to be hallmarks of your work is that you're not afraid to use darker shadows then they're needed and the very fluffy fur texture you're able to achieve. Great work overall. Keep on drawing!
