I'm not sure why this was declined but I guess it's because of the plane there in the sky (non-nature elements shouldn't be visible, see the rules for further information: [link]) Talking about the plane, I think it would look better without it, it's rather a distracting element and it shouldn't be a big problem to get rid of it with the clone tool. The composition is very good already but I think it might look a bit more balanced if you'd show more of the bottom part. Have a look at the rule of thirds: [link] Another last thing, I think the vignetting is a bit too strong. The vignetting effect itself isn't bad though.
The dreamy mood, the soft colours and the layers are wonderful, you did a great job here, keep up
Thank you! I think it was declined because of the overexposure of light.. unfortunately this was a spontaneous photo taken from the car so i didn't have the time to play with composition anyway I wouldn't want to get rid of the plane because it doesn't seem too distracting for me, I think it completes this composition pretty well. However I'll sure try to send over to your group any new nature/sky photography that will meet your regulations.
