Fantastic image.
I would like it even better if something could be done about overexposure in the upper right corner, but I guess you meant it like that. To contrast the low left corner...
It works quite well I think.

Very nice colors,the photo is very good.

Beautiful colors -- what a nice shot!! Thank you.

Hi Gael...I love the idea behind what you are trying to accomplish here and that is present to us, the viewers,  the trees in contrast ..the yellow of the autumn with the green left from the summer. There is an exposure problem most likely from the sun in the upper right. This can be corrected by changing your shooting angle or applying a filter to your camera and even sometimes in post-editing. The subject matter while good, is unbalanced and out of scale. I might have shot this from a distance so the viewer could see the trees and see them ins scale to the ground. As this image stands, all one views is a mass of leaves without anywhere to draw the viewer into the image. Try composing your shots with a single focal point. I am looking forward to seeing more images from you as you change and grow in your photography venture. ;=)

Very nice colours. Thank you for sharing.

As above,I love the rich colors.

Nice colours.
