Painting for FUN, or painting for PROFIT?
The focus on your art may depend on the above and change, limit, your direction.
If "Painting for profit", then you will look it as a BUSINESS. What sells most, how much, who are the collectors etc etc? This may pull you back from free, pure, creativity because you are guided by a potential market. Added to that. You will need to MARKET your work and that is a whole new ball game.
If "Painting for fun", well then. You are FREE to do as you wish. Paint what pleases without FEAR of having to sell and live by your creation.
Painting for fun and finding your work is loved and sells is the "Holly Grail". If only!!
