I was going to say those pictures would be really awesome in black and white but those clouds are so dark the pictures almost look black and white.
If it weren't for the trees at the bottom it would be hard to tell.
Nice shots, hope you stayed dry.
I tried cropping the trees out but it messed with picture and they didn't seem as good so I just left them how they were. I did manage to get in before the storm but I felt it starting to sprinkle and then it was down pouring within a min or two after I got inside.
