When that does happen, the tier lists will be altered and I request you keep in mind that you may have to reapply for the tier that you are on.
As for the tier changes, they are as follows:
$1 Tier - Will stay the same
$3 Tier - Removed
$5 Tier - All from the previous tier + 10% discount on regular commissions
$10 Tier - All from the previous tier + Personalized Sketch Drawn for you EVERY MONTH (With the option of "monthly themed" or not) (10 slots available)
$25 Tier - All from previous tier + Upgrade the sketch to a flat-colored lineart per month (This replaces the sketch-per-month) + 20% discount on regular commissions (3 slots available)
