this, along with other replies was well said. 'justatrick', speaking from experience, when you post something on a forum like you did, people are going to criticize. it has happened to me a lot. but at one point or another you need to take a step back and realize that everyone here is trying to help each other. and everyone here was just trying to give you advice as to how to better yourself as a performer. dont look at it entirely from a negative standpoint. i dont remember who said it here, 'but not everyone is perfect. there will always be some one out there who is better.' and if you want it bad enough, then practice like hell and be that better person. dont stop just because you think that people are trying to bring you down. that is not what was being done here. constructive criticism comes with the territory.
chin up sir.
