I am CrazyCowMM. A professional Minecraft map creator with over 5 years of experience. I specialize in commands, but that does not mean that I lack skills in any of the other areas of map creation. I've worked with many popular Youtubers including PrestonPlayz, PopularMMOs and Crainer and hope to provide my services to a wide range of audiences.
