I like the facevery small and sweet! As you say, the lips do need work. Look in the Tutorials section here there is an excellent tutorial linked from this site, here: http://www.exquisitedesign.com/tutorials/lips.html You can actually handpaint very nice lips with a bit of time and attention. With what you've shown you should be able to master the technique very quickly! The eyes too are a bit of an attention-grabber they are WAY too green. Even alarmingly green eyes are not that green. Try toning down the saturation, or maybe using a different, larger texture map for the eyes with better resolution if you're planning on doing close-ups.
