I saw something like this walking around Siena in Italy and decided to have a go, would be interested to know if people think it works? Click on it to see the large version (big though).
I think it wouldn’t look out of place as the front cover of commerical calendar – nice work!!
All I change is to try to level/straighten the tops of the two doors (not the arches) in the clips at the bottom and top to level them with the white frame around the centre photo ( except the one with the flowers as the white line in the centre is level already)
