Wow.. Great work! I love how the light poking through is creating a sort of ethereal effect. It feels like this could be a hair darker, but it's so close that I almost didn't even say anything. I like how there's a circle or sphere sort of thing that's pulling your attention up through the middle. Really cool angle and shot! This would probably do well on a 4x6 or larger!
Your right brightness could go down a little but its in range. There appears to be a little bit of moisture in the air, it looks misty up high. I guess it could be Indian spirits. Thanks for your take!
