What a sweet photo! I love both the original and what you did with it, your son is precious. I'm sure he will cherish that picture when he gets older! What a great way to be able to spend quality time with your son. I'm sure you want this bonding time to continue throughout your lives together, this will be something that he will always love to do with his dad! Very special!
How cool the photos are of you and your son. Adding the little adjustment makes all the differences in the way is perceived. I am the photos will have a lasting memory as he gets older.
