Okay, that was different than usual.
Let me start saying that we do have minors visiting this site most likely, and that kind of content isn't exactly very safe.
I'd like you to drop the predictions that you're going to be getting banned because we only do that when there's blatant rulebreaking, and we're pretty lenient on that. Most of us had previous experiences with DRAMATIC AS HELL Sonic (and others) boards, and we really don't want that to take over this place.
Now, if SSMB staff sent you such a ridiculously offensive message, then I've been giving that place too much credit. What a shitty place.
I've seen your art thread and frankly I think it's cool, especially that Thumbs Up Sonic. Art is not measured objectively like how you decide who wins a Scrabble game where the player with the highest points wins. It's subjective, and as such doesn't have a clear way to define. Therefore, first of all, STOP comparing yourself to other artists. That 14 year old might just be more dedicated to drawing. Hell, my little brother draws a lot better than me.
The world of artists (especially DevianTART) is a mishmash of several kinds of people. There are those who just draw for fun, the professionals that work on projects, and those who just like to feel superior to others by resorting to insults. Better to ignore them. I see you've been doing that by blocking all kinds of comments in your page already.
To improve on your art, I can only tell you to keep doing it. Whenever you're bored, doodle something. And just stop comparing your works to other people's. Keep drawing and uploading your art in your thread, we're always open to seeing some new stuff.
Lastly, welcome to SFGHQ/United. We're not your typical SANIC FANNNNNNNNNNS forum. In fact most of us already hate Sonic at this point.
