Good ones!
Good idea also to only bring out the contrast between the sunlet part and the part in shadow and to be working with lines and shapes and patterns and textures only, leaving out a horizon and everything!
I really can't tell which of these two I like better.
I like them both.
The first looks softer, for the lines are more wavey. I might wish for just a little less blurry foreground rock, that is all, I did some "scroll-cropping" on my screen and found I like it better if the bottom were cropped until the two little "waning moon" shadows are no longer to be seen.
The second looks a lot harder and much more serrated. Good to see how the dividing line between light and shadow is a diagonal.
