Not really sure where the confusion comes from. Personal expression in art is translating feelings, ideas or concepts you have into a work of art. If other people understand you through your work of art, you've done a good job as an artist.

Growth can come in many forms. Learning something about the artist, learning something about yourself while studying art, learning how to distinguish good critique from bad critique, how form and function of art work together, and so on.

There's nothing nebulous here. It's ironic that you go on a rant about 'art types' and demand critical thinking but then in some passive aggressive tone deserve that people serve you definitions on a platter.

And sure you can disagree, nothing I said implies you can't, I didn't call anyone mentally stunted so I don't know where that comes from.

This is a respectable attempt at an answer (bar para 3 anyway) and exactly what I so rarely get. I just get shut down because "it's art" and you don't question it. It's art so it's beautiful, it's art so it's valuable. The angry grunt from people or the silent downvotes here is the usual, so I appreciate this answer, or an attempt at thereof

I don't agree with what you say but I do appreciate your trying. Not enough karma to upvote you so a simple thanks must suffice. I wish we had a chance to talk in person on this.
