Hwei's kind of art

Now that a lot of people are making surveys (appereance, kit, type of mage, etc) about Hwei, I think it would be interesting talk about the main point of the character: his art.
What do you think his art will be like? We know that it is visually stunning!
What style do you think it will look like? impressionism, realism, surrealism? share your thoughts! :)
