Seriously, from the bottom of my heart — thank you to all of you who helped make this image possible, and to all of you who help make Derpibooru the amazing community that it is today. It's been an awesome six years, and I can't wait to see what the future has in store!
I would love to thank all the artists and OC owners who participated in this collaboration. Especially the artists who took time out of their day to draw OCs for others who otherwise may not have been able to participate in this collaboration otherwise. There were over seventy artists kind enough to help draw OCs for others, and I cannot thank you enough.
Though several artists really went above and beyond, drawing at least five OCs for other people, so I would like to give shout-outs to Arifproject, Binkyt11, CyanLightning, Darkest-Lunar-Flower, Dragonpone, Feralroku, LightningBolt, Succubi Samus, Toyminator900, and Wcnimbus. I also would like to give a shout-out to TheAnonShy and CyanLightning for the beautiful banner featured in this collab. Thank you everyone!
Also, if you're crazy enough to want the full resolution of the collab, which weighs in at right about 95MBs for a 18000 x 12000 image, you can find it at https://derpicdn.net/collab18.png. I do not recommend clicking that link on a slow and/or metered internet collection, because that will kill your bandwidth.
Once again, thank you! And Happy Birthday, Derpibooru!
