Nice photo, but the light on the ceiling draws my eye the most, which I don't think was your intention. Plus, if I didn't know the car, I wouldn't know what I was looking at, which may or may not be an issue.
that's the point, when we say a photo is like a 1000 word, we should not have the title of the photo tell us where to look ;). I guessed about the GT40, but I don't understand the photo. Please explain if you care ;)
Nice shot - think that it would have even more impact though if the wooden wall(?) on the left and the window on the right was cropped out, leaving only the ceiling and car.
This meets the challenge in some small way. I think you missed the 'key element' portion of the challenge. Your triangles are very secondary and practically non-existant as part of the overall composition or subject...
