I used Dawnbringer's 16 color palette (http://www.pixeljoint.com/forum/forum_posts.asp?TID=12795). I am bad at picking and shifting colours and I was in a hurry for this challenge, so I gave it a try.
Although I rushed the piece, I tried my best doing it. I suck at making tiles and so, and any C&C is welcome and wanted. I must practice the basics a lot, yep.
About the pixels... it's a RTS game based in Warcraft. Basically you're the leader of a group of cultist whose ultimate purpose is to glorify and even summon the Old One god you're devoted to.
