I do not believe Major Group 52 is appropriate unless you derive a significant income from those activities or are a well known practicioner. I think it would be like proving you have experience in a listed NOC for FSW, you would need to document actual and substantial work experience in theatre or the arts. You can see if anyone else has ideas, but I don't expect this is an easy category to qualify under. The few stories I have heard of even very well known artists and performers is that they are very strict in these kind of categories.
I think this group is really meant for professional atheletes, and theatre, film, music, visual artists and their associates trades.
