Ok holy shit that is some amazing composition right there.
The mace both acts as a line for the eye to follow from the sun to the moon, which reveals the knight's amazing trinkets.
Their blue silk helps contrast the warm colours of the sun, which helps them stand out more.
And GOD the neat little paint textures adds some homemadeness!
I don't really know about the use of text in this, it would be even cooler if it's handwritten. And maybe make the paper a bit aged, it looks like it's printed out of a school printer.
Other than that, BRILLIANT!
