"It's no good producing an amazing picture of something people aren't currently interested in. It's far, far better for you produce a merely 'good' picture of what people are clamoring to see at that moment"

I feel that this needs repeating for good measure.

One is stuck between the advice of "draw what you want to draw, so that you don't burn out, and the advice of drawing whatever the latest flavour of the month fanart is, whether you like the franchise or not.

So many good artists out there who never get any discoverability because they spend all their effort into drawing, and none on playing popularity games.
