I really like it, great job on that sprite. The only critique I can bring is that the shading on the legs doesn't seem to fit the very simplistic style of the sprite. Try some plain beige, or maybe 2 pixels under the dress as an underline, as you did under the hair.
Oh, and the lightened part of electronic cigarettes gets lighter during inhale, not darker

I really like that sprite

It is a good one. I am new to animation and know how tough it is..Great  job done..
