Suggestions for more rewards to be added? (Patreon)

In order to "step up my game", I have been thinking of adding more rewards that pretty much cant be stolen - this might include stuff like the already existing monthly fan-art polls, access to Discord, and feet/foot suggestion variants.

With that in mind, I do have some ideas such as in-stream sketch commissions, quick iPad sketches (when I obtain an iPad and switch over to Clip Studio Paint), monthly requests, etc. 

Although I listed some, are there any others you would like to see?
