I really like artsy-theo.
The art style of the old games is what caught my eye to begin with, but they have since retired that style. Artsy-Theo scratches my itch for more content in that style. I believe they've drawn every pokemon in that style and they'll occasionally put out new art in that style as well... though that's not the style they draw exclusively and they occasionally draw non pokemon stuff.
I don't believe I actually follow any "pokemon content creators" other than them.
