I continue to refine and reword the reward for it is a minefield if I am not careful.
But the gist of it is:
You or a loved one will cameo as a background character per chapter you are subscribed to. You can be a soldier, civilian, townfolk, etc. and your face will be recognizable and will not be a speck. Sometimes, you or your girlfriend/loved one may end up being in the foreground. It just depends on the needs.
I will protect your image and put you in a good light so don't worry. :)
You can withdraw your image if you decide to do so for whatever reason (i.e.: you may become a YouTube star, join the Secret Service, and now you don't want your face in a webcomic).
And the rest of the details are there on the rewards tier!
