Great art! I love this idea.
For those confused, I think I could help with the connections:
Olmak and Space Stone: Both create portals to other places.
Mask of Control and Mind Stone: The MoC can control minds, the Mind Stone creates minds.
Mask of Creation and Reality Stone: This is probably the biggest stretch, but the Mask of Creation can create things while the Reality Stone creates images. It works.
Mask of Ultimate Power and Power Stone: The names are a self-explanatory reason.
Vahi and Time Stone: Vahi is the Mask of Time, the Time Stone is the Time Stone.
Ignika and Soul Stone: The Soul Stone is the most vague of the Stones, being possibly sentient? The Ignika is also sentient. This one is my favorite connection.
