About "St Paul's Street"

This has to be one of my favourite views of St Paul's Cathedral. There is a point on a nearby street where St Paul's iconic dome reflects on two glass office buildings either side. A striking illusion is formed, highlighting the characteristic juxtaposition between traditional and modern architecture within the capital. I have depicted this view before using oils on aluminium, but never as a sketch, so it was intriguing to observe the difference in effect.
