I think Art is a completely subjective topic, whether it's musical art, paintings, or even blocks art. Here's an exsample, many people thing Van Gogh's sunflowers are a masterpiece, yet I personally find them to be nothing more than just a couple of flowers. On the other hand, many people think of Mona Lisa as just a regular painted woman, yet I think of this painting as something truly magical, as the eyes look like they always follow you for me.
Imagine you build something big for hours with much enthusiasm, yet when you present it no one seems to appreciate it, but when a player with better reputation that's better known does something mildly impressive compared to yours gets all the likes and approval. You will be disappointed and it's only natural to feel unappreciated after that.
Also, it will create another competitive segment where it really isn't needed. Ranking who's the better duelist between two people is easy, you just compare their experience and achievements, but ranking two artists is a whole another story.
