Water color-ry!I like the almost monochromatic look of this, though I do with there was a point of focus, or stronger directional line somewhere within. Nice feel, but doesn't necessarily draw me through the picture.

Seems lees about "Trees", maybe better for Skyscapes or Green. Not sure if the overall softness was intentional or not, but if it was then I don't think you quite got the technique right. If not intentional, then it's just not in focus, use a higher aperture. This is a beautiful subject, the sky in very nice.

i agree 2 comments there ^
something else: i'm not completly sure, but i've the feeling the picture is leaning a bit on the right.

The sky is beautiful... a little soft...I agree that its really not about the trees...

@ those who say sth. about the topic: its just that that i didnt find a better one^^

You know, I seem to miss topics a lot... don't listen to them. ;)

I like this, the colours are beautiful. My only thought is the foreground seems to be competing with what I assume is the focus of the image, the landscape. Not sure what to suggest though. Perhaps burning the sky a bit would add more impact to the top and draw the eye upward? It's a lovely landscape.
