Strange image... I had to spend at least 5 minutes looking at it to try to identify if this is a photo or a painting... And I still can't make up my mind. This uncertainty can be considered good. The image conveys a certain tension due to the apparent "fog" on the ground and the shallow clouds near the horizon line. It also reminds of those terrifying images of an atomic bomb exploding which is mental picture that contrasts with the peacefulness that this image transmits. Overall, the image doesn't have a "motif" per se, but the overall peacefulness is a very good motif. I once had a Powershot G1 and I'm impressed to see such an image coming out of that line of cameras (although the G1 X is a fabulous machine), so congratulations on technique and framing.
