youre makin strides, young gun ... keep at it
and get a metronome - seriously ... you'll be leagues ahead of your age peers if you develop a solid sense of time in your rhythm playing ... just tightens it up in so many ways ...
and learn about multitracking too ... at your stage of developement (and mine

) switching between chords and single notes typically results in suboptimal performance due to transitions .. so cut the rhythm tracks then go back and hit the single note riffs dead-on as an overdub
nice work
