Planned Changes to My Tiers and Rewards (Patreon)

Going into the New Year, I've been doing research and considering changes to my tier list and rewards. Here are the tiers and rewards I am considering.

 
$1 per month - Early access to my artworks, any animations I do. as well as previews and WIPs.

$5 per month - Hi-Res versions of my pieces. I'm also thinking of creating a Discord group and adding access to that to the mix. Nothing is set in stone on that front, though.

$10 per month - Alternate versions of my work, including NSFW material.

$15 per month - PSD format files of my works.

$20 per month - PDF Collections of my comics and my lottery pool. Basically, you'll be able to make suggestions as to characters I can draw for a bonus piece I'll be doing every month. Suggestions will be chosen at random every month. 

Does this seem fair? I'm hoping that this will both make my rewards my accessible and (if I'm being completely honest) encourage higher donations.

Additional tiers and rewards may be added as my fortunes improve. Again, be sure to let me know what you think.
