It looks nice to me, but two more bishops and another knight seems too
much.
So, I suggest this: R; Cr; N; B; Cb; Co; K; Q; P; Cb; B; N; Cr; R.
In this way:
Cb= Crowned Bishop, moves like a Bishop or a King (Dragon Horse, Crowned
Rook(Cr) = Dragon King);
P= Prince, moves like an Archbishop (Bishop + Kinight) (the Concubine (Co)
moves like a Chancellor (Rook + Knight))
This looks like a better way to use the board.
