I totally thought that same thing about the "pit sniffing" but I just love the composition of the rest of the photo aside from that. 1 does seem a bit overexposed. I'll see what I can do. Thanks.
1)
Best of the 3 IMO, except for the underexposure.
2)
I agree with D-B-J that the vignette is distracting. I would also have preferred the background to be a bit further away and out of focus -- the sharply focussed lines and imperfections in the background keep drawing my eyes away from the subject. And yeah, arm pits are bad
3)
The angle seems a bit extreme here. I can't see enough of the face and the forehead is overemphasized, which isn't all that flattering.
