Nice. I would straighten the horizon a bit - seems like it is a degree or so off to me although it could be just a bit of wide-angle distortion and an uneven crop.
I'm thinking a bit later those clouds probably really lit up orange and red. Did you take any photos later?
This was part of a series of photos in a time-lapse of the sun setting as mentioned in the post. I will be sharing more photos and the animations in the next few days. I used magic lantern for the time-lapse and the bracketing option for the HDR photo. The clouds looked truly amazing at different points in the time-lapse which is one of the reasons I like capturing sunsets when the sky is cloudy.
Sounds great. I look forward to seeing the rest.
