I think the picture looks nice, and the shading is soft and pretty. I love the colour pink personally.
A tip for lips if you're wishing to try different things (sorry if this is way out of date!) is to try doing them without such hard outlines, like just shade them in softly with a transparent brush C:
Lip colours in real life are often based off skin tone with a bit of pink so if u were to brush a soft pink that was based off the skin tone on the colour wheel of the program u use, perhaps it would be to an effect you like
None the less hope this is helfpull, The way you did the lips here is alright as well. Just a suggestion for u to try out and play with C : .
Anywho. I shall take a peek at the rest of ur stuff = 3= perhaps this comment doesn't apply any longer : >
