I have no idea how to solo or play anything i havent heard before, any tips on just playing? (no idea how to word this properly)

Ive been playing for about a year or two and Im pretty solid at playing other people's stuff (learning songs by ear, fingerstyle, jazz (other peoples songs) n other stuff). But I still cant play anything original on the spot. If I try just playing, I never know what note to play, or when to play it. Any tips? Im trying to learn to play like maya delilah, and/or african style guitar.

(I also finished guitar tricks fundamentals and part of the funk tutorials a while ago)
