I like the concept, but I feel like its missing some things. For example, there is no fire, earth, water, or even air evocation. There are also many overlapping things with the druidic metamorphosis.
This is what is displayed in druidic metamorphosis:
The Druidic Circles [ex: horns or antlers grown from the head, fur or feathers sprouting from the body, extraneous arms resembling flightless wings, moss developing externally]
This is what is displayed in yours:
Conjuration appears as faux life growing around the body such as: feathers, serpentine or crocodilian scales, permanently blooming flowers, or vines forming around the limbs.
My advice would be to look more closely at the metamorphosis effects of the others- and see where they overlap. A good start, but im unsure if it will work.
