So recently I commented on this submission http://www.furaffinity.net/view/4594568/ and was subsequently blocked by the user  Remyplains because "Yup nice to see that this community supports Budding artists, since this is the first work I ever did, Douche "

This is the first time I've been blocked but not the first time I've seen or heard of someone completely unable to take criticism. Firstly I never insulted him or his 'story' but pointed out three points which he could easily improve and were noticeable without reading fully.

Sure you can ignore criticism and only pay attention when people praise you, and there's certainly no shortage of that in the fandom, but you'll never grow if that's what you do. Unless you can acknowledge some of your own weaknesses there is zero chance of you improving on them.

Short message. Grow up. If you post online you are opening yourself up to positive and negative reviews. The positive ones are there to make you feel good and the negative ones tell you how to improve.
