i agree with the person above me, it does the design a disservice to put it on such a light color (and a color that's so similar in shade to a large part of your design).
the purple and navy read very well, the black may be a bit harsh.
I love it. You really captured such a lovely, whimsical, dream-like vibe with this design. Something about it is very calming to me when I look at it. I like it best on the darker colors as the design really stands out. $5. Awesome job man.
