From the colors I can't tell if that's smoke from a fire or one heck of a thunderhead cloud. I assume it wasn't a fire. One way or the other this is a great photo. Yep, I agree. Ominous is the right title.
A nicely composed photo and good view of the landscape. I like the darkness of the clouds threatening to dump some rain closing in on the scene. Nice lighting in the foreground. Good post-photo work to set the mood. The image seems to be folding in on itself, with the trees in the foreground seeming to lean in towards the center. As if the image has been pinched at the top. It could be just a trick of the angle and perspective. Good work and thanks for sharing.
