Query: Difficult yet beautiful

This puzzle took me a week 2 do. Usually a puzzle of 1500 pieces takes me 3 days. Once you get the bright colors tooken care of you have the black pieces to worry about mainly the black horse part. My suggestion is to divide the pieces in top 4 piles, 4 piles consisting of the 4 different pieces (the way they are cut) and do processes of elimination, because once you see there is a pattern in the way the pieces go. It most diffently teaches you patience.
