The only thing that doesn't seem to look right is the "Solar energy today creates a cleaner Tomorrow" sign. It seems to be written on the fog in the air.

that's the poster part... unless I read the contest goal wrong (look at the comment area) they said they wanted typography

A poster that blends into the rest of the street? Typography is optional and nothing wrong with it but it just looks like it's floating in air. It doesn't look as real as the other signs.

err Umm.. the whole Image is a poster.. that's why the text is floating

Skewed type doesn't work well, & letters are not uniform sizes...

oooook.

very nice
