Stop being so shy on the mic. Spit like you got a pair....lol. Anyway, this wasn't bad at all for a first spit....might be because you had a little help editing, but either way, shit was alright. You fall off the beat a little but it takes time getting your flow down perfectly......I suggest you spit the verse about 5-10 times all the way through before you even record. This helps you get comfortable with the verse, so when you read it, you know exactly how you're gonna spit it
