scaling up a painting

oil, 40x20

Scaling up a painting from a very small (6"x6") to a large (40"x20") is a challenge. Simply transferring the image and making it larger rarely results in an interesting piece. Therefore, since my interest was really in the sky I decided to change the format to the dynamic vertical. Still the land mass needed some interest, yet simplicity. That's where the real battle was. I am still not sure, but it is almost time to frame. As they say, a painting has many stopping points. Any suggestions folks?
