Does Anyone Have Any Ideas To Improve Your Voice?

Hey Guys, I'm 14 and i love to sing/rap. I wish to pursue a career in the music industry, so far i produce but i would love to get better at my singing. I practice all the time and i feel it's getting better i just need something that's going to boost my voice and make it much better. im getting braces soon will that affect my voice ? if so in a good or bad way. I would like to sing music such as, Ed Sheeran, Wale and Future and maybe Justin Bieber's type. Thanks so much i really appreciate you reading this. #ambition
