The colors and composition are gorgeous. It seems you have duplicated the picture, applied a blur and set its opacity to ~33% in Photoshop. Am I wrong ?
Your instincts are very good. I applied a Gaussian blur to the duplicate layer, then set its mode to Overlay, then reduced the opacity (don't remember by how much). I did the same thing to http://milov.nl/2680 (very subtly) and http://milov.nl/2709 (not so subtly).
Oh yeah I've decided to use the name Milo above my comments from now on...
