I was thinking of doing something to say thanks to my $8 tier subscribers, but it can't be anything that excludes the 4 and 6 tiers from content because I always said $8 was just a voluntary support tier. Nevertheless, I really appreciate all the people giving me a little extra cash based on nothing but the goodness of their hearts. Howabout if I dumped zips on the $8 tier with all the work available at the lower tiers, but at full res? (I typically draw a page at 3000 pixels (vertical) but downres it to 1600 to post) That way, no one is excluded from the content, but I can give the top tier a bonus.
