Hmm...well, your character already looks nice. But if it were me, this is what I would do differently:
Change the hair color to a darker shade. I recommend raven. (The hairstyle's fine.)
Slightly fuller, wider lips. Bottom lip slightly bigger than the top lip (like it is now). Leave the cupid's arrow. It's sexy.
The face is too oval. Give the jaw more definition.
Widen the nostrils.
Remove the blush if you have it on. Can't fully tell with the lighting. It just doesn't look good, imo, 'cause of the perfect skin the characters have. But I'd love to be proven wrong. lol
Experiment with the eyelashes. Go for something a little longer.
That is what I would change. But like I said earlier, the character already looks nice. Save that look, then load it up again and experiment.
