I can't figure out how to get rid of this smudge, even after cleaning it. It's the dark line to the right. Anyone got an idea?
It's a hair on your sensor. You can blow it off with a static-free blower, or avoid shooting at small apertures like f/16 or lower, or just clone it out in three seconds in lightroom or photoshop.

That's a tree.
