Study Of Light

Another one of my older works, about 2 years old. This time I was trying to paint the light and do a fast painting practise. So this was a rather quick sketch for me (9hours), also because I have an Inspiration. Its not as detailed, I want to keep it more rough, the main focus is just light. I have some reference photos for the architecture from St.Peters in Rome. The photo was not mine but It helped me a lot by this picture
