I don't think the lighting was ideal in that situation. You've got hot spots on your faces in various places in the pics.
Also I don't think self pics are the best for this. You're focusing too much on the camera - when the timer is gonna go off, etc. You can't really compose a shot from the other side of the lens very well (and I've tried it too - they just don't come out as good). I would definitely have someone else do some photos for you. If you were closer I'd help out, but TX is a bit far 😛
It's just these types of photos come out so much better when you two are focused on each other and you're allowing someone else to see the scene and compose a shot and capture something less posed that's more personal, etc.
In the link with the 6 photos:
#1 - Background is blown out and distracts from the image by drawing your eyes away a bit. Her eyes are a bit dark, and a hotspot on forehead. Focus is good, as is DOF.
#2 - Similar to #1 with the background being a bit bright and the hotspots. I don't particularly like the way your heads are positioned.
#3 - I like the pose - the harsh light on her right arm is taking away from this photo. I think in all of them they could have benefited from a diffuser panel and some fill flash.
#4 - I don't like the pose - hands in your pockets...harsh light on the side of your face and your face creates a shadow on hers which darkens her face more and her eyes completely dissappear. Hard to see the effect on a self timer, but easily spotted with a pair of eyes behind the camera.
#5 - Good photo - if you could get rid of the blown highlight on her forehead again it would be better.
#6 - Good pose, don't like the crop. Her hand looks a bit out of place with so little of it in the shot - I would have her move it up further/move it more to your chest. Top of your head is cut off...not a huge deal, just personally don't like it here. I think this would have been better shot in portrait orientation to get more of your bodies in the image.
That's my $.02
