What attracted me was basically the silhouette of the sky made by the building. By the way, the sky wasn't that dark, although it was cloudy and going to rain. The shadow was added from imagination to give the sketch a bit more depth.
I'm trying out the Waterford watercolour paper for the first time and I really like it. The cold press surface absorbs water well, and brings out the texture of watercolour beautifully. The paper is a bit off-white which I'm still getting used to.
