At the Eyjafjallajökull's Feet

At first I didn't consider this image worth post-processing. It grew on me for months and just recently, few days ago, I stumbled upon it again, while culling through my images again. This time, however, I had a clear vision of what I wanted to achieve and convey with this picture. It all was there, sitting in front of me. I just couldn't see it until just now.

As always - I'm happy to hear your thoughts. Especially on toning the image. In one frame I have almost three different landscapes - harsh sun, clouded shade and rain/fog - at the same time. It was quite a challenge to get everything in place. If you have any suggestions on this - don't hesitate. :)
