"There seems to be an somewhat of an assumption that everyone who visits the galleries is or considers themselves to be an artist" I'm a poser hobbyist myself, and I welcome criticism if it's constructive, and even if it is for hobby purposes most folks still want to get better at it. If you are willing to show folks what you do, you have to ready to take whatever they say, good or bad, if it is good take it, use it, and drive on. If it it's bad, brush it off, and drive on. If people can not take constructive criticism then maybe they shouldn't post their images for the world to see. Criticism must be done in a tactful constructive manner.

Ask me a question, and I'll give you an answer.
