Okay this will take some explaining but I'll try my best.

There's a strange behavior I've noticed over the years back in my time on deviantart and it's a problem that persists even today. I don't fully blame art community websites for this but they are one of the main issues, most if not all comments are all purely positive without the slightest bit of criticism, comments should have more substance than "wow cool" or "cutest thing ever" cause a lot of artists just stop pushing themselves after a while.
Worse still are the ones who get angry at someone giving out legitimate criticism or art advice, they sit around under the assumption that their art is perfect despite all the obvious flaws they believe to be correct. I'm not saying I'm a great artist by any means but I do know my flaws and shortcomings (perhaps too much) and I try to work through them. More people need to keep themselves open for input and be ready to learn new things, it's a major part of being an artist but some folks forget this and stagnate sometimes for a few weeks, sometimes for years.

This is why I call it devianyart syndrome, I've seen artists with art from several years ago thats identical to their current art, you should always strive for some degree of improvement even if it's just a dumb hobby to you, I'm well aware that everyone progresses at their own rate but still give it some effort, it's only natural to.
