English not being my mother tongue, I did some research to embed as many visual puns as I could into my picture. There are at least 4 of them here, can you spot them? :-)
1. Easiest one: the head is floating in the air like a balloon, obviously, the girl must be light-headed.
2. There is a strong light at the end of the road, and the girl is heading to it: she is light-headed.
3. It's getting harder now: the giant hands over the horizon suggest that a very big creature is standing there. If this assumption is true, then his head must be that strong light: the giant is light-headed.
4. The whole scenery is distorted, as if the viewer himself had vision problems, like when you are light-headed.
All the photos (field, biker, hands, moon, sky) have been shot by me, no stock photo. Hope you like it!
