So you know / follow StanG?
Are these arts newly draw in last months? If so that's pretty high production value.
Does he do OG stuff / commission as a business? Or just draw as a hobbit, and commissions are more like pocket changes (hence more Fanart stuff).
If it's the latter, then he'll very unlikely commit to LD, since it'll only be temporary passion.
And passion burn twice as bright burn out fast.
I know tons of artists that doesn't care about money, just draw whatever they want then move onto the next thing.
