I worked in Central House in Harrogate for a while - and these were a couple of interesting pictures I took whilst there.
The cloud - the weather suddenly changed, and I was able to capture the blue sky reflecting in the windows whilst at the same time capturing the dark grey clouds and raindrops on the windows.
I particularly like the strong contrast in these pictures.
The remaining picture was one taken on a very cold day following an overnight snowfall.
I think it captures the feeling of cold.
