The commission reward tiers have been removed for the foreseeable future, due to the high amount of workload they produced for me. I'm currently still finishing the due backlog up in between pages for the buffer, and intend to have the very last of those sent out by the end of this month, so if you sent me a prompt before the discontinuation, don't worry, your art is coming. IF YOU STILL CURRENTLY HAVE PLEDGES SET UP AT REWARD TIER LEVELS, PLEASE REVIEW THEM BEFORE UPDATES START AGAIN. I don't want people paying way more per page than they'll be getting money's worth. If need be, don't be shy about discussing refunds with me.
As for future rewards. At $3 per page, you get a new Poppy wallpaper each month. At $5 per page, you'll get to see "Worldbuilding Wednesday" posts, which are fun weekly infodumps about various irrelevant details about Flora and minor characters. At $10 per page, you'll get to directly request specific information you want to see expanded on in future WW updates, barring the obvious spoiler territory.
These are just minimums, by the way, unlike the commission rewards, you're perfectly free to set your monthly limit right at the reward tier and still access the content if you feel so inclined. I'm open to suggestions about other sorts of rewards people would be interested in seeing as well.
