I think you have a lovely tone to your voice lwood, I really enjoyed listening to your songs - I thought the last two were really cute! Sorry though, I'm not able to critique your voice like an expert would
About your dry throat, I can only suggest that you drink lots of water during the day (every day) to make sure your whole body is hydrated (which you probably do - don't mean to teach grandma how to suck eggs! Not that I'm saying you're a grandma....obviously...just an expression) I've just noticed Daniellehmusic has just said that too - oooops!!!!. Also acid reflux can cause inflamation and irritation and might be worth investigating. Stacey :D
