Yeah, I came to realize it's the theme I am using for the forums. It downscaled my 720p itself, probably reduced the quality.
Conan, I'll probably have the other shot up later. Just let me know if you want a different render of the cliffs. The smudge and transparency is an isolated incident, I rendered at 1080p and forgot I am taking map screenshots in 720p, so I downscaled the 1080 and left over some greenscreen.
