>>1631272Stuff in red highlights the lineart for her eyes, which are a little weird, with some extra kinks and nodes that shouldn't be there. Also, the inside and outside lines of the pupil don't match perfectly. Make sure the nodes on the inside are in the same place as the outside. Like someone said before, using the ellipse tool can help you get started. You would then just convert it to a fill and edit from there.
The stuff in blue are lines that are too straight. Give them handles and curve them a bit.
Lastly, the green is referring to the blush lines. Not really a fan of strokes. They stick out more than anything else to me.
