Summer Postcards (word)

Now that I have completed the full word, I need to start working upon a way too develop and 2 colours (max) I dont want too over complicate the image, so I wish not too add colour into the type word), but instead the background.  

Below is some of the development which has been going on in the last day or so ... feedback again please. 

So that is some more development from my original concept.  I have tried too use limited spot colours.  Although I can push the use and number of colours further I feel the piece does not need it, and that if I do use more, it could distract the audience from the detail in the typography. Feedback would be grand!
