Hi Irene! I like this image with its pastel colors! IMHO you don’t have too much space on the top. It balances nicely with the dark tufa on the bottom. However I do think the tufa is a little too dark as very little detail can be seen, but I would not suggest lightening it much as I like the contrast with the water.
I always believe the image working is in the eye of the beholder. I really like this image and think the way the stones cascade outward works to draw the eye out. I personally find landscape shots hard to produce the results I want so am always respecting those who can.
So glad you decided to post. While most might recognize the tufa formations, I think the high contrast and condensed presentation does give this quite an abstract quality. I think the color does as well.
I think for a straight landscape image capturing the tufa at Mono Lake, I think the tufa is too dark. However, as you’re presented this, I think the darkness and contrast is working very effectively and I think you were successful in depicting the “ancient and surreal nature” of Mono Lake.
As far as too much up top, I think that’s arguable. I am really enjoying the color and the “to infinity and beyond” impression that the space provides up top; adding to the surreal nature of this. I also like the longer exposure that is ghosting out the water.
I keep looking and trying to think of a crop - but don’t see one that would improve this. I think the intended darkness and the abstract nature of the tufa combine for a successful presentation and take away from Mono Lake.
