It's hard to pin down your style. I liked your blues song, which reminded me of Billy Holiday's style. I happen to have an orginal ceramic phonograph of "Lady Sings the Blues."
The rap song started out sounding like something Annie Lennox would do.
I have been playing guitar since October 1974, self-taught. I just picked up a guitar one day (grandparents' little classical guitar) and started picking the arpeggio to Credence Clearwater Revival's "Who'll Stop the Rain."

My mom gave me her old student folk guitar and Mel Bay's Book of Chords. And it all started there. I've taught myself to play classical in a non-standard format. I will take sheet music and transpose it to tablature form, finding the easiest way to play it. I like Corelli and Damas-Tarrega.
I've played Led Zepellin I through IV and the "Rain Song."
I've played the entire soundtrack of "Jesus Christ Superstar" and sang all the parts, and I do mean all of them. I've specifically worked on my voice since 1987 and can range from baritone into the lower end of castrati. But usually sing tenor. In so doing I've developed a volume that can make your head ache. I've seen people flinch when I do "Dream On" by Aerosmith because I hit that note with a pure tone.
I've got a 4-track recording machine for cassette but I don't have a way to record digital, though I would like to get one of those kits that just jacks into the computer.
My current practice set includes these songs.

Just to name a few.
I don't have any digital recordings, so I linked the originals to give you an idea of range of material.
