Aww doood, I'm going to make a critic!

Ok, so let's aim for the coloring, shall we?

Color Choice:
I like the way the soft/bright colors get along so well OwO d The clothings' ones couldn't be any better Although I think that, if you're willing to evolve more in later artworks (which a background by that time, I presume), I'd suggest some less saturated colors (and I'm speaking specifically of the hair :3

Shading:
Now, the shading on the clothes is soft, suggesting a nice comfy indumentary I specially like the way they're darker on the back! And they also seem to fit the colors you've chosen well

Highlights:
On the matter of the highlights, there's not much to say :3 The ones on the hair look splendid, but maybe a little too obvious, if you get my point. Maybe trying to make it zig-zag shaped? However, it still looks good on this :3
About the shoes highlights all I've got to say is that they look a little 'out-of-lightsourse'. According to what I see when I look at this, dood, I can tell lights coming from the top-left, however, her right shoe tells me otherwise But that's a minor thing now

Overall - Good paintin!
