What do I think?
Okay,... what I think.
I think you should go for a composition. Find a good screenshot. Take the screenshot. Done. Stop all the editing crap in screenshots! Now humble, ink, and batfink are my squaddies and I love 'em, but I take a different path than they do with regards to screenshots. I prefer them unedited, but well set up and taken. I think the game has all the effects you need built directly into it, and all you need is get the right shot of what is already happening.
