Sophia I forgot to mention... that you played that lesson from memory is impressive, especially since you haven't been at this very long. Do you listen to blues? Maybe some old players (actually dead players, like Howlin' Wolf, Muddy Waters) that have some fine piano going on in the rhythm section? Early "John Mayall and The Bluesbreakers" albums has some great piano.
I notice that you keep good time with your metronome, or drummer, which is good, technically speaking. But fiddling with the meter is part of what blues players do to carve out their take on a tune. All of the players I've ever played blues with liked to hit just before (push), or just after (pull) the beat. Push gives a sense of momentum; pull can have a laid back effect. I know you're just beginning these lessons, and offering up the idea of playing before or after beat one of a measure might sound counterproductive, but this is a way to liven up your licks.
