High Key or Low Key?

I really had no idea how to tackle todays theme and I was more concerned with the fact that my baby boy lost his first tooth last night and I wanted a photo to capture that gap in his teeth which is oh so adorable. Since making memories through photos for the kids is why I'm doing this it seemed a good idea.

What I didnt count on was how hard it would be to get the photo! This was the best of a bad bunch to be honest and I dont even think you can see the gap very well either :( although his lovely smile makes up for it :)

So I'm sure this photo will be either high or low key but I dont know maybe someone can enlighten me???
