1974, I never done painting art so I am not sure if I can do an art job like yours. I am a stain glass art work for a hobby, do windows for my home and some friends. I do think that once an artist always an artist so you are still an artist.
Sometimes an artist thinks the things he or she does are very easy and that anyone can do them, but this is not true. It is easy for you only. Some of us are born with this.
