I think this is a good start, but I think there are ways to make it better.
Having one Dragon King and Dragon Horse instead of two
Adding a pair of Kirins in place of the second Dragon King and Dragon Horse
Giving the Dragon a different, but still powerful, move, such as Bishop+Nightrider (BN0) (The current one can easily force mate by itself, which is usually too powerful for a chess game)
Otherwise, I think this page is good enough to be approved.
