This is the HBoS (formally Bank of Scotland) headquarters which stands high above Princes Street Gardens on The Mound. I took my Derwent pastel pencils/crayons with me today to add some colour.

It was a little messy but I like the effect you can achieve by adding a lighter colour on top of a darker one. Blending the two. I will stick with the pastels for a while as I could of spent all day experimenting, if only I had the time.
