The hair seems a little bit weird, but that's probably because the shading is not very visible. The shirt has the same problem.
I like the pants, but the scarf falls behind them sort of weird, so it looks like you messed up or something. Also, the waist is to straight, but a belt or a curviness on the jeans might fix that.
The shoes are adorable
Overall, it's a pretty decent first try. There are just a few little things to work out, and it'll be great
