Hello and welcome @ForestFable,
Bright blessings on your commitment to your path and starting a new piece!
It seems logical that your previous paintings may have contained unintentional spell work, and now that you’ve chosen a path they could be very intentional spells. I speak in possibilities because only you are qualified to determine if your art is an expression of your magick.
There’s another artist, @Neriss, who is considering their work as a medium for spell work. The two of you have similar attitudes toward the physical world and might have more in common. 
Sorry… that was a very long winded way of saying that we are an eclectic community and are open to sharing our stories, listening to yours, and responding to questions with answers or references.
Merry meet!
~ Lisa
