I Think It Needs Work

I tried to finish this model, but I'm having a bit of trouble creating a good poly flow. I think I understand how to do the eyes, but the mouth and nose elude me. Every time I try this I also end up with more polys than I think I should for a "low-poly" first draft, but that's just me trying to be detailed when I shouldn't. The circled parts are those I'm a worried about.


Any suggestions for how this thing should wrap the face? Should I make the cheek less defined?
