Ooooh, a color-shading style!~ That's cool! I'm used to this style of coloring and yours is nice! Especially her eye
I'm not a pro yet, but...may i give some advice for you?
-You can add darker skin shade between her two eyes(It's a half-image now, but it's ok) and her cheek bone area to make her look more realistic
- You can blur some pinkish red color to create blush on her cheek
- And a little but smooth highlights on her forehead, cheek and chin! It will make the drawing nicer
- Be adventurous with colors, color-shading is fun when it comes to color picking. Don't be afraid to pick vivid or dark color....When i was on the beginning of color shading, i tend to use soft-light palletes until my mom told me to be brave with colors. And you know, the drawing turned more lively!
I'm sory if i said something wrong! I hope these may help you
