This picture reminds me a lot of the style of graffiti or street art that was popular with skateboarders when I was younger. It's still popular, as far as I can tell, but for me it's a trip down nostalgia lane, back to a time when I wasn't even a teenager yet, and I had crushes on skaters.
The slightly psychedelic effect on the yellow rose is the result of my experiments with salt. All in all, I like the floating effect, as if it's all a dream against the blue sky. Perfect for a bedroom!
