Practice, practice, practice....

I have an upcoming trip and want to do some 'on site' sketches so I decided to practice some on what I'll be seeing when abroad.This a Watercolor sketch of a photo I took when we last visited Barcelona, I think this is the Passieg-de-Gracia building. The area is beautiful but what caught my eye was the contrast of the orange roofs against the quite blue sky.
