Composition: Very intresting. You have strong diagonal lines with excellent forced perspective. I question the crop of the photo - I think I'd like to see the louvers framed to start more to the left for a pleasing line that keeps the eye in frame.
Background: great muted color and soft focus on the grid.
Camera Work: (Focus/DOF/Exposure) Great DOF and focus on the foreground elements. The edges are nice and crisp and add to the color difference along the edge.
Post Processing: n/a
The Challenge: Wonderful abstract, great muted colors and compelling lines.
My Opinion: I like the pallette and color balance very much. The muted tones and dreamy quality are wonderfully evocative - it gives the feel that this object is from the fifties because of the blueness of the white. The composition of lines is only slightly off to me - an angle that gives a greater incline to the louvers or a crop or shift to the left would also help, IMO.

I like the arrangement and subject. Lighting looks a bit flat making the rest of the image appear dull. Fiddle with the levels a bit as an experiment to enhance contrast.
