Sketch reward possible comeback. (Patreon)

Due to the fact that I've been losing income at an alarming rate I might have to bring back the sketch reward tier. But if I do so, it won't be at the original 30 usd (that's less than half of what I charge for one lol and it's a lot of work to keep up with them. I still haven't delivered some of the owed ones from back when I had the old tier)
The new price should be around 50 usd.
Tbh I do this because it seems like my patreon isn't alluring enough to keep people in with just my art/discord/drive and I can understand considering how heavily people repost my work everywhere for free... I'm cornered to do this again.
If you have a suggestion on what could I do to bring more people in, I'd love to hear you out.
