Hi xhunterko!
You cannot expect to achieve new goals or move beyond your present circumstances unless you change.
These people are being curel to be kind, I think. If anyone says something to you that you don't like, regardless of whether they said it for your own benefit or just to be nasty, don't get angry. If what they say isn't true, then just shrug it off. If you know that it is true, use that critisicm as a tool to improve yourself.
This is just my opinion, but what bengoshia said wasn't fuelled by some hate for you; he said it because he is passionate about this hobby and he wants others to improve as well (including you). The best way to improve is to reflect on yourself in a critical and objective way. If you get emotional about critisicm about your work, and choose to block it out, you are also blocking the path to progress!
I just posted some new stuff over of pixeljoint (I'm a noob too!) and got loads of critisicm. But I wish I got more! Really! Every failure is a chance to improve. Many people on the forum noticed things in my picture that I didn't, and I thank them for that.
I don't know, I think I'm ranting a little bit here, but what I'm trying to say is that you should keep trying, but maybe you should change your learning process to take into account what other people have to say, even if it is not always a friendly compliment. Then you'll be sure to improve!
