Those poses are awfull. Motion so poor as my English. Also whats wrong with her legs?
Diar Natasha, I lend to you 4/5 becouse in totall you painting is not bad at all.
Also cat looks nice.

Looks like she's ... slipping? If that's supposed to be a running motion it feels a bit off (and her leg disappears behind the other one - not to mention the cat/tiger/little critter's legs), and the trees, woah, thick trunks for small branches. XD The aspect ratio, angle, and outline could be polished a bit, but coloring and shading looks good. Nice effect with the snow too, though how about blurring the edges, or making them a little transparent? Overall, not bad.
