More tiers/incentives? (Patreon)

First I wanna say thank you to EVERYONE for your support~  As of now, I think I want to add some extra tiers, but I'm not sure what I should add.  I'm still sorta new to this Patreon thing, and I feel like maybe just access to some .psd files doesn't seem like enough.

I was thinking of making adding a weekly Caturday poll to the $1 and up tier, or maybe work in some kinda refreshable monthly tier that gets like...a free drawing a month.  Well, not a free one, but i think you understand what I mean by that.

I'm more or less brainstorming, but if any of you have any ideas, feel free to post them here!
