How do I do this? (Patreon)

basically week 1 i'll decide on what to do for my full picture to give to patreons and those in the respective pledges can help! and week 3 of each month i'll post the second one!
if I am to post more than two then there will be 1 pic week one, 2 pics week 2 and 1 pic week three and if there's more than that then i'll figure something out
but between main pictures i'll post wips, sketches, etc

as far as voting go, i'll make a post with a link to a poll with various ideas, those who have the higher pledges will get a link before hand with a poll that they can add ideas too, there may even be an exclusive skype or telegram or even facebook group for us to discuss ideas~
