Thanks for all the nice comments
I did shoot in RAW, and I'm right now working on making a better version. The colour is harshly exaggerated in this first version, along with noise, so I'll try to reduce that.
Poly, I sort of thought the same, maybe not nukes, but definitely some massive explosions, perhaps steam explosions. It looks crazy
Zxan, I knew you'd have some knowledge about these clouds. I didn't keep an eye on them, but I believe they started to quickly dissipate not too long after I took the photos. I don't recall hearing thunder.
edit: Ok so here we go!
This is the final cut I think, everything is how I want it, maybe some strong colours, but it looks fine I think. Got some good input from you guys at least.
Final cut.
Here is another version, it's basically the same, except it's got some more clouds in it and a little more noisy, but nothing special.
Zxanphorian version.
Here is the whole thing, no processing, barely any cropping, no resize. It's 9k, so it's a little big. I like the genuine colours in this one, and I do think I overdid colours in the other versions a little.
HUUUUGE.
Oh and the .PSD for this is 200 megabytes. Right now photoshop is sucking up 1.6GB ram and probably 2GB pagefile :{
