I think I know why I don't feel like posting in artwork anymore. I can never come up with anything constructive to say. ^^'
Even if it's nothing construction, I can tell you that every artist loves to see a comment. Even if it's just "thanks" or "nice." It's always better than nothing.
Too many artists get discouraged when you have lurkers who say nothing. Just consume it but never say anything. They don't realize people do that and they just think no one likes their stuff and it discourages them from making more. So ALWAYS, please, anyone who lurks and it reading this, say thanks or say something to an art piece you enjoy.
It really helps the artist out.
