This is a great idea, too bad it is a little out of focus, also the frame is a little tilted. other than that I love the picture and success story behind it.
I really like how you have it set up. It would be nice to see a picture of this with them in front of it when they get to highschool. A bit blurry but great memory and capture.
Wonderful demonstration of growth. However, you may lose some points overall due an apparently complete soft focus, although the focus on the daughter's eyes seems slightly better than the son's.
That's a plus though. An older & wiser photographer once told me in family portraits "Always set your focus on the Momma's eyes because she's the one who pays the bill!"
there is a problem with the focus - i like the idea of the 'younger years' photo as a backdrop - very effective. Depending on your post processing package it's quite easy to straighten the shot when cropping - check out the tutorials on the site for further details - nice attempt
