my thoughts
ok take this with a grain of salt... I won't be offended

All in all I liked it. The video doesn't have any surprises in it, but then the song doesn't either, so it works.
OK ... so I've watched the video a couple of times now, and here's what I see:
1) Nothing wrong with the overexposed video on the guy. The two different outfits for the guy however ( white striped singing, black playing guitar )is bad. Oh I don't know maybe it works. Nothing you can fix now, so don't worry about it.
2) The girl on the other hand needs to give us some sense that she's not in the same scene with him. Not sure what that should be. At one point you put her in B&W, which might work, but then you do it later to the guy at 1:57 which seems WAY out of place... his clip is our mainstay... It has to remain consistent.
3) Everything is so tight. The camera is always close. I get it that you want to give that personal connection, but I'm thinking maybe we need a little relief from it at times. We get a tiny bit of relief from this when we see the guitar, but its not enough. You know maybe a far half or full body from-the-side shot or something for one of those guitar strumming shots ( maybe at 1:26, since that's not lining up with the music anyway

)
Well, maybe not there because you have the shot at ~1:40, but you get the idea
4) When we see the girl, you're even tighter, which could work, but the most important thing about her is her eyes, and right at 1:00 you cut her eyes off, and you do it again at 2:29. ( and remember if you end up having to respect TV safe areas for whatever reason, this is going to be even more pronounced )
5) speaking of eyes, the fading eyes thing at 2:51 - 2:59... at 2:56 or so you've got to make her right eye ( audience left ) fade out at the same time as the other eye. It's creepy distracting otherwise.
6) nitpick... matte out her stray hair at 0:43 ( just fade it into the white )
Hope this helps!
