My parents Anniversary card

Yesterday, April 6th, was my parents' 53rd wedding anniversary. This is the card I made for them. The main message is clear enough, but in case you can't read the smaller bit, it reads as follows -- The hummingbird is considered as a symbol of eternity due to the movement of its wings.

I'm noticing that the green heart looks glued on, but it's actually cut out like a window.
