Ayo man. You're not half bad. But when you have bad audio feed, the best thing to do is to write out the verse you were spittin' (keystyle it when you post the audio) so we can get a better understanding of what you're saying and how you can improve upon it. You may not wanna speak so loudly into the mic since that is what causes the distortion.
Keep at it, but remember that if you're gonna drop audio, there's a forum here made especially for that. This one is for if you wanna drop some lyrics/a keystyle to get feedback on. I'd like to see your work around here more often though man. :tu
P.S. A lil' breath control can go an awefully long way. Keep spaces open in your verses for you to breathe and structure your bars so that it will come off more naturally when you need to pause for a split second to refresh ya lungs. Your flow will be much improved by this......
