I know everyone's taste is different and I am not the art police, but as a professional artist I find her work to be an expression of her inner emptiness. It is devoid of feeling, connection, even the barest understanding of color theory. It is bland, flat, and lifeless. Sure, there is a measure of technical proficiency and a kind of "correctness" that seems a desperate attempt to appeal to a commercial interest.
I'm on the fence about purchasing the work, since those funds may be seen as benefitting JA, (or possibly alleviating a small amount of the financial burden on her family.) I can see why someone would want to own one of her pieces as a kind of "outsider art" or naive-style work. It is interesting to see pieces done by the mentally ill. I knew of a schizophrenic painter whose work is fascinating, (and VERY good.)
