This is really nice looking! Great effects!

Here's the thing about Strange,why would he necessarily become less important,merely due to his demotion from Sorcerer Supreme?
I mean,he is one of the most accomplished mages on the Earth dimension,regardless of title.Seems to me,he would see losing the title as a huge relief(as would befit a magical mindset.There are no set backs only new opportunities.),freeing him to make decisions based on his own recognizances,and not some arbitrary title.In addition,wouldn't pretty much every Principality in any dimension be more then happy to offer their services to a mage of Stephen's caliber,a former Sorcerer Supreme?
The Eye of Agamotto?Even in the real world there are numerous different talismans and symbols that start off with "The Eye of..."the Eye of Budda,the Eye of Horus,the Eye of Isis....but why bother with already established artifacts?I mean,a simulacrum of the Eye of Odin would be pretty bad ass,imagine Dr. Strange with access to the Odin Force.Throw in Munin and Hugin,and all of a sudden he has all the forewarning of mystical threats he ever had as Sorcerer Supreme,and a cool visual.Ravens,are cool.
Cloak of Levitation?I seriously doubt Strange would need a cape to allow him to fly in the first place,but I farther doubt the Cloak of Levitation is the only magical cloak in the Marvel universe,hell I doubt it's the only magic cape with a ridiculously high collar.Why levitation?Cloak of Invisibility,Cloak of Invulnerability(Strange going toe to toe with Thor)Cloak of Darkness,connected to the Dark Dimension,like Cloak or Shroud.
If Strange is supposed to be a "hero" wouldn't the logical thing to do,be get up brush himself off and regain enough power to be the hero on the level he was before,without the mostly unearned magical force becoming the Sorcerer Supreme entails?
Heroes,go on quests.Strange,should shave a few years off("Yeah,I have had this vial of water from the Fountain of Youth for years,but I was expressly forbidden to use it as Sorcerer Supreme."),gather his resources,and quest to gain the power to fight the demons,and Elder Gods he used to.
But naw,let's just downgrade him form a B-lister to a C-lister and be done with him for a few years.Yay,Marvel!
