Meticulous, sad.
There's quite a lot of detail- that's what I noticed first. But the detailing is also quite repetitive. My impression is of an artist fixated on a particular grievance or tragedy. In the center-left is the clearest iteration of a some sort of symbol, and the rest of the wavelengths are seemingly noise that contribute to the repitition of the symbol. But there's that clear beacon, signifying some kind of tragedy that time eventually confuses into a blur but is nonetheless immutable and unforgettable.
