Creating Tiered Icon Variations

Icon Tiers:
1. each level needs to have one or more easily noticeable difference(s) between from the level before & and after it.
2. each level needs to be instantly recognizeable as the item it's based on
3. no palette swaps unless otherwise stated
4. needs to be of the same high quality as the original icon, no exceptions.
5. avoid icon's top right corner, and always put pips (pinned at the top of this channel)(edited)
