Interest in subject is not there. I've seen some really awesome photos of shades. Unfortunately I can't remember who here took them. Anyway, the idea needs a little more thought.
Not sure what to tell you on this one. I might be missing something, but I don't see anything that makes me want this one on my wall. Sorry, but hey that's what these challenges are for. You win some and you lose some. I am still trying to get the hang of it too, so keep trying and don't let the occasional loser like me get you down about your photos. You might have wanted to try to get something more interesting in the reflection of your glasses. Maybe a building, a beautiful woman... anything that would grab the interest of your viewer.
2 - Meets the Challenge by a bit of a stretch. Main thing in my opinion is that this seems a bit snapshottish, although the concept could 'work', however would need refinement. Sharper and more attention paid to detail, make this better in my opinion, but not sure what you were aiming for.
