Let me know what you think, but don't be too harsh on me. Still have the "newly wed" high.
That's an oxymoron.
It's a snapshot, might as well use a cell phone.
Lighting: very harsh and directional. Yes, you can use this type of lighting but in this specific image, it doesn't work.
Exposure: seems well exposed. Hard to judge on non-calib monitor.
Composition:
Is that a vase of a cowboy boot?
Flower at bottom right - got no light.
I like the w/e it is that the rings are on - leading lines

BUT...I'm all pro non standard crop sizes (they make you think about the image) but here, there's just SO MUCH OTHER STUFF going on that rings are barely noticeable.
Next time you want to take a picture, ask your self "what will this image represent?" If you say people, then you shouldn't have demolition derby smoke w/ one person standing somewhere barely visible. If you say rings, then maybe put the ring on the cake, put them on flower, make then STANDOUT from their environment, not blend in and disappear (like it is here).
Now the non-harsh part:
The best part about taking a crappy shot, is that once you learn & understand why it is crappy, you can only improve. Congrads on the wedding
Keep shooting and improving
