I've kept it bottled up for a bit, but now it's time for me to fess up about the importance of constructive criticism.

I've been seeing a trend of artists and video game developers getting really salty at someone for providing any form of criticism, whether it's constructive or not. Like, hello? These people helping you by telling you about the flaws of your art/game you made, not insulting you in any way! I've been in a similar position as these artists and devs by rejecting critique, but I eventually started accepting them (and I'm still open for critiques, even if I didn't ask).

So my helpful advice is this: when someone provides critique, don't lash out at or curse out these people (or anything like that). Just politely accept them in a very mature manner and you'll surely improve on your work in a long run. Rejecting criticism by putting up an angry-toned "critique discouraged because this is MY art! >:U" disclaimer in your art descriptions or something would only make things worse for you as an artist or developer.

In conclusion: critiques always help if they're constructive, not destructive. Accept, and I'm sure you'll do better when you're practicing your artistic and video game development skills.
