Random placement is random, Cash. XD But I wouldn't say the spritework as a whole is completely original.
Even though I did them myself, I still used the VX/Mack stuff as a base. Because I really wasn't fond of redoing all of Tristian's 300+ maps, I sort of just went over the existing tileset I was using. But hey, it looks unique. That's all that matters at the moment. =)
