great shape on the upper lip .. and I really like the crease around the mouth.
The nose could use a bit more work tho - give it a bit more detail over the ridge of the nose.
I dont know if its just me, but I think you need a bit more volume to the back of the head.. just a little.
over all : comming along great ..
