keep going, don't let life slow you down
Good work on this song, you are definitely improving.
If your music is what you do, DO IT MAN. Don't let other people tell you otherwise. People who see you enjoying something and succeeding at it will often try to discourage it and make it seem like something horrible or unnecessary.
To that I say one thing: prove them wrong. Your brother should be nothing but proud of your achievements.
about the song itself, I think that it is much improved from your previous works. you did a good job on the variation at the beginning, I love the glitching you did on the bass/kick. the lead was very nice, good work on the chords for that. your mastering is improving as well :)
keep at this dude. I'm sure that at some point, it will pay off for you and your brother will finally realize how good it truly is.
