On #2, about 40% from the left, is something that looks like a funnel forming. I suppose it's not, but if it was, the colors would be really interesting for a funnel formation.
I would warn you to stay from the blackhole of photography but you are probably already within the capture vortex so there is no escape. You have most likely had someone tell you that one of your images was great and they suggested that you should be selling your work.
Enjoy the ride. Although some people think that photography will suck the lifeblood out of you, as well as take all your money, there is some good news.
Scientists used to surmise that once you are sucked into the hole itself or at least near the primary vortex, (bear with me, I'm making this up as I go), you are ripped to shreds by the huge gravitational pull. The new theory is that if you get sucked in quickly there is no disintegration and you emerge from the other side in a few billion years with no harmful effects. See, it isn't all that bad.
by the way, Autumn Day, very nice!
