That's cool I do to there's a lot to learn form others! I like the feedback exchanges. I think its also fun when people do mini poll's on their artworks looking for their audience to make decisions so that everyone has a collaborative spirit. Puts more love into a project and people can be more invested in the piece on a whole.
Yeah I'm alright no worries. But not really feeling motivated enough to do anything right now after what happened. I tried to help someone since they were frustrated about a drawing which they have done. I stepped in to motivate her and offered her some good ways to fix her drawing and bam!, next thing I noticed was I was getting bitten hard for that. I just shut up and left that convo. Wasn't in a mood to fight with some immature person.
I'd block them, some people have shown they can't handle feedback. If that person is going to be that way they will more than likely try to have their friends gang up on you. :/ Sorry dude that sucks and its happened to me too. When I couldn't handle feedback in the past I usually just sauntered off for a few days after saying thank you. I would be unmotivated but I always try to come back to it and use it.
Like when some people put up journals or posts on what they are doing and share the process to completion, or even do polls or journals leaving it up to the audience on what they want to see in a piece. It can range from simple art to tutorials.
