I think that you should start off with your most favorite colors. then, do a quote that inspires you. and try to do a abstract painting.
for example: "live and love loudly, share it and don't forget to dream big." that is the quote i go by and it inspires me.
Not sure what graph you’re talking about but i know that when you play an instrument the pitches are different regarding the note and tone you play
VERY good
I like the intro you wrote maybe add another sentence that is stronger for the last sentence
