Alfaro's looks to be a 1 piece lefort which is more straight forward. Not sure about Gunson's. It could be a 3 piece lefort to flip out the front teeth more which 'kisses out' the lips more than Alfaro. Alfaro likes a stronger chin. Keep in mind that Gunson's proposal also 'goes with' your wanting to enhance your cheek area. In the event you asked Alfaro if the maxilla advancement would make your eye/cheek area look more recessed, that could have factored into his design where there's no forward advancement of the maxilla.
I think I'd like to get the lips pursed out a bit, it might look closer to my ideal (for myself not comparing to celebs). I told Alfaro about the nasolabial folds, I would think he would want to forward advance the maxilla.
Would it help if I showed a side profile image? I'd be able to PM it, but I don't want to overstep that boundary you have mentioned already, just wondering if it'd help explain / show my situation.
