hmm
tail looks more like a tentacle or something, if shes a catgirl or foxgirl or whatever she is it should look a bit more furry, hair looks a bit clumpy too, bit more detail in those areas would make this look alot better. but I suppose you mainly just concentrated on the hips and boobs. her right arm looks like its been chopped off too, I know its meant to be bending round but it looks like its just a stump, the end should be a bit more rounded maybe?
