I've updated the rewards, so there's now two new ones: a monthly giveaway reward and a sketch reward! You can check them out on the sidebar there, if you're interested. I'll probably add to the rewards later on (I'm kicking around some ideas), but for now, I think we've got some good rewards up!
If you have any suggestions for rewards, or if you'd like to ask a question in general, don't be shy to message me or post on here! :)
