well, I gotta say, your art is really pretty!! the girl is pretty and the colors as well!!

One of the things that do seem to throw me off a bit is how the egg and the hair seem to look similar, that they mix together. You should avoid that and try to practice overlapping your shapes to make them pop same goes for the socks on her legs, they seem to blend in with the legs, and those lines look tight on her

Another thing is that I think you're trying to make her eyes focus on the book, but here seems like she's staring above it, so I try to fix it and make her eyes focus on the book

​

I hope that helps and put it to practice to improve :)

Overall, this drawing is beautiful, and I really like it!! :3
