This is what happens when diplomacy fails!Only one piece of cake left... how could such a terrible thing happen? The Princesses of Equestria had come to the Crystal Empire on a friendly visit, but how quickly it had all turned sour. Though attempts were made to placate the warring Alicorns with fresh cupcakes, their battle was too far gone to be stopped. Soldiers from the Royal Guard stood by uneasily, the castle staff looking on fearfully. Not even Shining Armour had been able to intervene, forced to flee the field of battle, calling out bitterly "I am not cleaning that up!"The crystal ponies will not soon forget the day their castle echoed with the sounds of conflict as the Princesses turned on each other. And it would come to be known as The Pillow Fight of the Princesses.Wow! So this picture took me a long time to get right. Still trying to adapt to my new rig and new operating systems, and it's proving awfully difficult. It probably didn't help that I insisted on making this picture so huge, making even my new laptop have to stop for a breather every now and then. But oh well, it's all done now, and I'm enormously happy with the end result! Hopefully you all like it tooI'm continuing my new visualisation of magic, depicting it as magical sparks as opposed to a solid field like I used to do. I also got to experiment with showing this magic in action (i.e. throwing a pillow). I hope it looks all right to all of you, and any feedback about it would be appreciatedMy Little Pony: Friendship is Magic is property of Hasbro and
