That's a really good one. I wish the painter would have dialed up the OSL from the lantern a bit, it's a cool deviation from the standard Flower-Knight-Holding-Flower.
There have been so many amazing versions of the Flower Knight since KDM came out. I think this one remains my favorite even if it's not as technically excellent as the one you linked:
Infinity: Caledonia, Steel Phalanx
BMG: Batman, Green Arrow, Law, Bane, Leto Joker, Suicide Squad
SAGA: Anglo-Danes, Anglo-Saxons (Almost...), Vikings
X-Wing: Standard/Epic (Wave 8)
Misc: RelicBlade, Relic Knights, Zombicide, Imperial Assault (Wave 2)
