The oil leak looks like it could be leaking around the filter cap area but the filter cap and drain cap drain plug was tight. Maybe Filter cap O-ring went bad. I changed the oil myself a little over a month ago.

^did you put some oil on the new o-ring before cranking the cap on? If you don't lube the o-ring, it can wrinkle or tear when you tighten the cap.
Oh, and when you're looking for leaks, start high. Unless they're pressure leaks, gravity makes them start from the top.

The oil filter cap threads into the oil pump housing, which is bolted direcly to the bottom of the engine, inside the oil pan. There's only an o-ring style 'profile gasket' between it and the main part of the oil pan. Is your oil filter cap maybe cracked?
