thank's for your comment.
After posting it I thought that I had been overenthusiastic daring to post this one. I am overenthusiastic about photography since I started it abt. a month ago, shoot too many and spend too little time in postproduction. I actually still have to learn how to do many things in post pro, next time I shall try to post better adjusted images.
I think this is quite effective Kuuan, simple repetitions like this can work very well. I'd like to see the tiles on the bottom row flush with the edge of the photo ... should be an easy fix to straigten it up & crop in photoshop or similar software if you want to change it. Nifty
