1. Can I use a pseudonym on business cards, or at public exhibits (like a library art exhibit)? I know it's legal and acceptable for writers, but I'm not sure about artists. I hate my real name and really don't want anyone calling me that; I can't do initials because I hate both first and last, and having only a username on a card just looks weird imo.
2. There are many critique groups for writers, both online and local groups. So far I haven't seen anything like this for artists. Art sites are primarily for posting art rather than critique, so asking there is not very fruitful. Are there any groups or communities anywhere whose primary focus is critique?
