Unlike my previous windowcolor princesses the design for my window of Spike the Brave and Glorious is my own rather than based on a window from the series or the movies. While there is a Spike window in the show, I think that one has way too little Spike, way too much crystal heart and way too little color in it while not including some of Spike’s more recent accomplishments with regard to pony-changeling and pony-dragon relations into account.  
With the Crystal Empire being the site of many of his accomplishments and his greatest adherence I included the tower of the Empire and the crystal heart in my design as well as Princess Ember (lower left) and Thorax (lower right).
