Thanks guys! The fog was extremely thick, causing the huge stars, but the curves probably could have been fine tuned a bit more for the highlights.
I've never been happier with a camera than my 5DmkII... even better now with the cool weather. I constantly have to resist the urge to mod it (but terrestrial/people photography is a greater priority for me).

Oh well, back to all the study... hope to see everyone's amazing work again after exams!
