Is There a Difference Between Art Writing and Writing on Twitter?

I like pieces of writing where I get to bring lots of different tools and different parts of my brain to the table. One thing I've really enjoyed that my followers on twitter don't see is that I'm writing a bunch of like prose poems for a gallery in Sweden. They have shows they show paintings and they have writing about those shows but they don't like traditional art writing neither do I so I just produce like wacky prose poems for them.
