Lindell, I do. But I think you may not like my answer because it requires drawing with a ruler for the best learning process. Dont get scared please it is needed for the artists and after few drawings it gets way way easier.
This requires few sketches and following 2 point perspective in pencil. When you have guiding lines you will be able to judge about relative sizes of the objects in the painting.
I had article about moon shine. I have couple of the sketches attached there, you may try to look at what I (kind of) mean but then to fly to youtube to get better advice with the video guidance how to draw.
