Ignore this if you don't like people being a bit egotistical. I try not to be like that, but right now I just feel like sharing this with whoever cares to read it.
As I review my pictures, I'm really surprised that I'm able to make such impressive pictures. I say make rather than take because I'm not just taking a picture and posting it. An HDR involves processing, and when it's processed I edit it further to really dial up the dramatic qualities. To me, drama is what a really good cloud conveys, and I'm very pleased with how good I've gotten at bringing that out in my pictures.
