Well you've presented it very well. I think it's a really great idea. You're basically building your own world step by step. Everything from the paintings to the stories really help make that universe real. I think it's really smart to do it that way. In the end, I'm sure your story and world will come together quite beautifully. You're doing all the leg work up front so you know where you're going as it all comes together. Good stuff. I wish you luck in it! The two brothers definitely stick out in my mind as great characters.
