Intersting dynamic of shapes, though the interruption of the lamp-post is I think rather a distraction than an intersting addition. I'd alos have been tempted to either crop out the cars or completely get them in shot: this way they look accidental, rather than a deliberate part of your composition. A good start though ...
The red is bright and the sky is visible but look very titled because of the lightpost. Also I would have shown all the red car matching the red building behind it.
