I'm beyond ecstatic that the new caster is Pictomancer, but the visual FX feels... almost unfinished.
The stone and ice spells have low-resolution and extremely un-detailed textures. Like, for a split second I thought they were placeholder textures. These need more details, and/or perhaps making the textures have actual paintbrush strokes in them would go a long way in making them fit in FFXIV's aesthetic while still being their own thing.
Also, in the trailer, Krile's pictomancy had an extremely high amount of particle effects like sparkles, as well as strands of multicolor ink trailing being her brush strokes. I think adding these effects to the spells will make them look like proper magic using aether as a paint medium instead of what we have now.
