I applaud you and the level of detail that you have packed into this piece of art. Every single piece of Princess Celestia's armor that we can see has a different cutie mark on it, displaying her devotion to every one of her little ponies. Each pony in her many battalions are a different color and wear a slightly different set of armor. The scale of the little ponies versus the foes that they face down is very apparent, and Celestia's position far above them, waiting to leap into the fray if her little ponies start to falter, speaks to the power that she holds and the prospects for victory that they face against the Changelings. And the Changelings themselves, each one uniform in color and posture, disappearing into the mountainside in the distance... Overall, a masterful piece that has immediately been used as my computer's wallpaper.
