Slightly change on Tier(s) (Patreon)

Hi! As you noticed (or not) I made slight alteration on Tiers, just how the rewards will be distribuited:

- Graphite and Crayon (Tier 1 and 2 respectively) will still get the rewards through the posted Images only, hoping that won't receive so much quality degradation as I always post them in the best quality possible.

- Pastel (Tier 3) rewards instead beside the posted Images will receive the link for the .png versions and a video process (hoping to get them at 1080p once I have a better device) always on the end of the month.

- I will (try) always to guarantee 3 artworks and at least a NSFW version of these and if I don't reach the quota I'll add it for the next month.
