Hi Cody, let me tell ya, you made the right choice to post your singing clips here. I was terrified when I first submitted my first recordings. But they weren't of songs. They were mostly examples from lessons. I had no singing lessons prior to that, just a whole bunch of singing sites and programs that I tried to learn from. The guys on the forum really helped me with their advices on what I should improve on. Took me like 6 months to finally record my first cover and subject it to criticism here.
So my advice would be, start from the basics, like a singing instructor would be an obvious choice, but if you don't have that option, any basic vocal program or youtube channel will do wonders, do the exercises, then post them in the technique section.
At least that's how I approached it.
Oh and, you're gonna need a quality mic sooner or later if you're serious about singing. Got my Rode M1 on sale, for like 90 bucks.
