reward ideas/thoughts? (Patreon)

so im thinking of ways and rewards to offer, to make sure if i get alot of support im not overwhelming myself, but still offering rewards. example, i have the monthly/bimonthly icons for 5 dollar tier. thats fine for now, but if i get like 30 people, i wont be able to keep up. how do i make it still worth it, but maintain a good workload. i may remove the 5 dollar one and maybe make it a stream request thing when i get that worked out, or maybe raise the price of the 5 dollar tier by a buck or two? what do you guys think?

:edit: ill be toying with the tiers in the next day or so. i have been tweaking and twerking stuff, trying to think of good balances, so please offer any ideas you think will be fair :D im thinking of  maybe upping the 5 dollar tier by a buck or two to compensate for the icon and making it lined instead, like i have adjusted, or maybe remove it entirely and come up with soemthing else.. tell me if you think thats fair =3. im also thinking of making the arts bi-monthly, so that way when some people come in, ill have the art split between months. people who joined a month apart or so will have thier art the next month, so i have a split work load, and ill compensate it some other way maybe
