You're doing well Kiwisa. You're getting a nice tone out of that guitar ... it's just a little out of tune though.
One of the easiest and most effective ways of improving your sound is to be as close to perfectly in tune as you can. If the problem is the guitar, like a bridge that has moved a bit, then get it fixed. If it's old strings refusing to tune up, change them.
Squeaks and flubbed notes, timing errors, those kind of mistakes ... they just last an instant, they come and go ... an out of tune guitar, however, lasts the whole tune, and turns even the best playing sour throughout.
I can hear your dedication in those tunes though ... good on ya
