I for one think thats a great idea - The model is looking great but spending time in one area is the right move - but plz leave some room for some rigging (even if basic) as a posed version of this...

thats a very nice ref pic - nice find there
Rhetoric Camel. Also useful ref for a skin texture

nice gum line and set of teeth - again looking very good so far - apart from that noise- keep it up

other angle looked better - this one makes him look a bit swished.
