I'll be honest here.
Yeah, she's absolutely adorable and I like the little space ommannder thing going on there. But... I have to say as I started looking at the legs I saw these chunky things which didn't quite fit the rest of the image.
The picture overall is cute and you used a nice set of colours, kudos to you but just work on the legs. T'is all ^_^ Look forward to more cute stuff from you!
