I love the rich colors in contrast with eachother, your logo cleverly placed on the bottom of the ashtray!.. and the splashes of green vines on the wall and between the pavement! Makes for a lovely picture! :)
I am always drawn to contrasting blues, reds or yellows. The location of your watermark works like a charm though if you were a smoker it might have been even more amusing to be placed under one of the seats, along the narrow strip. Cheers.
