413360 Vector Logo

I need a high quality iconic vector logo based on the mock-ups attached, the logo needs to be similar in design and concept, but different and unique enough to be able to be copyrighted. Elements that need to be in the new logo are a basic circular design with the skull and the moon face transposing or completing each other with some kind of spiked crown and or other exterior embellishments. The theme of the logo is: elements of darkness, please keep that in mind in your designs. The logo will need to be provided in PSD format for resizing and color variations.
