updating patreon page/question on free sketches!please read and offer thoughts! (Patreon)

so as said, I'm going to be fixing things up around here! I'm making a new banner between images, and going to make tier icons, to pretty things up! I'm also going to adjust tiers slightly, adding some more clear wording, plus if possible my old idea reworked

this is the big thing I need help on. I know raffled and such are very much mostly not allowed, but what I wanted was originally not  a raffle but randomly gifting patrons with free monthly sketches which I would pick and cycle, basically every month i would pick a number based on number of patrons,  take suggestions for a theme and etc, and cycle through patrons till everyone got one, starting form one end to another. the thing is, I dont know if this still counts as a raffle which I don't want to do, because i get why raffles aren't included, but I do want to include it int he patron description as extra incentive. does anyone know more about this, or how to make it okay, if it isn't already as described?
