that looks alot like paint daubs, and blur.
The whole vector thing is basically using shapes, filling it with solid colors, and putting it on top of everything.
not to mention the shapes are not pixel-based. they're created with mathematical equations so they can be resized and instead of stretching pixels, it just multiplys without getting all pixelated because... yeah, i forgot how to explain it.
even a plain square can be a vector as long as it's using vector graphics.
