The above illustration is actually only the top half of a larger image. As far as composition goes I think this is an improvement on the original (see below). The reason for this is the reduced colour palette and the shape of the canvas. A limited colour palette tends to bring a piece together more harmoniously; there’s fewer colours to clash against each other and the use of values is more noticeable, thus you can be more subtle with their use.
As for the canvas shape/size, the key difference from the original is that the focal point for the viewer is much more clear – your eye is drawn to the window cleaner; he is in that right third (a compositional mainstay), and he stands out very clearly.
The image below is the original. While it’s not an awful picture, I do think there is a bit too much going on. It’s also not clear where the eye should be led, and I think it’s fair to say that the window cleaner stands out a lot less in this version despite the colours remaining the same. Suffice to say it would’ve taken probably less than half the time to complete this had I just painted the top half – you live and learn. I could be totally wrong of course, so feel free to let me know what you think in the comments. As always, enjoy!
