I love both backgrounds and the great photo of your "boys". But I'm more drawn to the blues. I think the earthtones make me think of mens suits which your dh and ds are obviously not wearing.
Here are a couple of quotes I like.
It is not flesh and blood but the heart which makes us fathers and sons. ~Johann Schiller
For you see, each day I love you more
Today more than yesterday and less than tomorrow.
~Rosemonde Gerard
If you are going to add text to the LO I would suggest adding some above and below the picture. I think it will help balance the LO and fit well in the color blocks you have already defined.
I hope the suggestions help you find the way you like the LO best!
