This is an interesting subject and very well treated (although I don't know how more of these blokes don't fall to their deaths). I think that the strenght of the vertical elements here is a little diluted with the large grey area on the right and perhaps a little tighter cropping might be worth considering. Regardless, this is still strong image.

Very cool.
could also fit into the work topic..

i think that this would be a fabulous shot even if cropped to make it into a square format.
but even as it is.
its nicely done.
love the intensity of the edges of the windows!

Yes, well seen and well composed.

superbe cadrage, avec le reflet du laveur de carreau. on dirait qu'il nettoie les nuages

I can't add any other criticism to this photo that hasn't already been added, I really like the colors in the windows, as usual great photo!!!

what a job. nice capture!

I think ksenia had the right suggestion: a square cropping would make the photo stronger, mostly for cutting out the wall on the right side. I think it distracts from the pattern and repetition of the windows and would make the window-washer stand out even more. But otherwise, it's a good photo.

looks like he's cleaning the clouds off the windows to reveal the sky in the reflection... nice!
