Rosa: The Flower of Life

This is a crappy first time thing (with no lore sorry) so be nice UwU.

Rosa is a ranged, A.P. support that excels in bottom and mid lane. With the flowers of life by her side, she crushes her enemies and brings new life to her allies. (Skin possibly undead Rosa) She's very closely related to by the looks of things.

Q; The Thorns of Life: Rosa brings forth an army of roses. If cast on an ally, it heals them for 3 seconds (very rough, no exact times/AP scaling). If cast on an enemy, the thorns dig into them and for 3 seconds it deals damage as they move.

W; Visionary Flower: Rosa places a flower that acts as a ward in any place. It reveals a small area around the flower and if stepped on, the flower closes, releasing pollen and granting a larger vision area and slowing targets in the area. (Little to no damage)

E; Charm of Nature: Rosa creates a small, aoe field of pollen. Enemies in the field take damage and after 3 seconds, are charmed (towards Rosa). Allies in the field gain a small armor and MR buff.

R; Death in Bloom: Rosa channels her energy into her plants and creates a large aoe area that cannot be escaped. In this area allies gain an AD, AP and attack speed boost where as enemies gain a debuff that lowers speed and they take damage over time.. When stunned, knocked back/up, polymorphed, etc or if cancelled, the area dissipates and the buffs and debuffs are removed (it's a channeled ability so of course cc will cancel it).

Plz be nice. Rito accept this plz and if not Rito, Valve plz.

(Concept arts greatly appreciated)

EDIT: Shoot, I forgot a passive.

Passive; Petals of Disruption: After Rosa casts an ability, she leaves a trail of petals for 3 seconds (disappear after 6 seconds or something). Allies that follow the trail directly (no going backwards through it) gain a small MS buff where as enemies (going any way through it) get a small MS debuff.
