This is really lovely. I like how you blended everything and the colors. You made the right choice by washing them out. I'm guessing you used the texturizer for the background? Also the text is simple, yet you know how to work it so it looks great. One thing is that the red in the grunge that is blended with the rainbow doesn't have the same shade of red. And the pink grass needs to be blended in the roots. Slight details that I think most won't notice, but still should be pointed out.
