Feedback: Posting of 1 or 2 warmup sketches a month on webtoons/deviant art/etc. (Patreon)

In an effort to advertise the Patreon exclusive warmup sketches and increase the webtoons views for higher ad revenue, I was thinking of uploading a warmup sketch or 2 to the places I upload my art. Idea being I post a lower res version of it with the caption of "get the high res and see more for just $3 a month," plus the usual patron shout-out attached to the bottom of the picture. I could even put it to a vote for you guys to select which drawing goes up. Maybe the previous months sketches? I could also perhaps color it too since the inking is already done, so you're also choosing what gets color. Thoughts?
