Reeeeally amazing work, as always! I've been a Varus Main since I started playing League (In fact, I actually found League after finding a picture of the Heartseeker Varus splash while searching for cupid references LOL).
I have a few very minor suggestions, most of which I see already covered, like Conqueror Varus's R being recolored to be more red/gold than red/purple. A big, big thing that would be a huge quality of life for Varus would be if when casting his ult, the tendrils that come out to root nearby enemies were slowed down a little bit to better match the actual time it takes to root nearby enemies. As of now, the tendrils get on top of people and kinda sit there for a minute before the root takes effect, and I'd love to see the root pop immediately when the tendrils snare them!
Another super small thing, for Heartseeker Varus, could you maybe add a more pinkish ring around the area his E is affecting? I see the roses and everything but it has a small grey...
