Hi Martin,
Welcome to OPF! Are you from Holland?
Anyway, we're glad to have you with us and that you jump right in!
Your picture is remarkable for repeated triangular shapes and mostly grey blue hues with streaked of gold in what looks like lakes between hills.
There's a horizontal ridge of material stretching for about 3 cmm or so from about 1cm from the middle of the left border of the picture. Is that the dam? That disrupts the picture, which is fine, if that is intended because that effect is not at all subtle.
If that ridge serves as the bottom of the picture and everything below (ie the lower half of the image) were removed, then the picture would become an interesting panoramic view unique in its coloring and with sufficient shape to keep one's eyes exploring.
Another satisfactory picture can be found after cropping away the left 1/3 and the bottom 3/4 cm.
Unless on is transmitting ieas of chaos, which is OK to do, an image should be only as complicated as required. Photography requires making decisions to exclude as well as, of course to include.
There is no doubt that you have chosen a great subject and found an interesting color palette. However, there is, to my eye a lack of unity of concept and the presence of disorder which is not comfortable. The latter can be a great characteristic of a massive image and maybe it will work large.
Now these ideas are only my take and discount the critique according to your own sense of your picture and what you intend.
I think you might consider some different versions. It would be helpful if the original picture was posted so we can get better orientated to the dam and then perhaps give a more helpful response.
Thanks for sharing, I do hope my $0.02 is helpful.
