Quote - You are right. If they didnt have the guts to post something nasty like that out in the open, that makes them a coward, and by doing so they are being sneaky.

I just hope that is the last one i have to deal with. I have decided that seeing how that person thinks my artwork is a waste of space, i shall make even more spacing up that waste.

 

I haven't signed up for the critique group yet, as I'm trying to find more time creating my own artwork, let alone giving other artists in-depth critique.

It's good to know that the forum moderators here are willing to help with this issue (abusive mail).

I second fivecat's points.    
Also, I would suggest that you take most critiques with grains of salt, and pay attention only to the ones from artists whose works are really good or (you think) are better than yours.

When I have more time posting and critiquing artworks, I might decide to send out invitation mail for some of my favorite artists (whose works I really admire) to critique my work.

Just my two cents.
