I am a traveling artist, I always make special sketchbooks to depict my travels. This art book I filled with watercolor sketches during my last trip to Istanbul. Allmost all the sketches were made on location, I added some notes later. Turn the music on and watch the video till the end.
You'll be surprised ;)
