During my stay at the Nationalpark Müritz in August, I was not only there at the sunrises, but also at some sunsets. The most spectactular one was this one, with a great layer of clouds partially glowing, partially already shadowed, reflecting in the lake, the Müritz (Germany's largest lake, if you discount the Bodensee which is shared with Austria and Switzerland).
Using my Sigma 70-200/2.8, I focused on these things, brought in the sun very large, and focussing on the colours. Post processing is a minimum, using Lightroom, increasing gamma, contrast and just increasing vividness a tiny bit, but not in a mood-altering way.
I recommend to use large black magic.
