Hi, your design is exactly what I'm looking for !
Can you do a version where the design is filled in the same as the outline, a silver version & one version with a line going through the center of the circle like this φ. Then I will award you the prize !
I have uploaded the logo with the required changes on Deviant art. Please check this link https://artworm1985.deviantart.com/art/Da-Mutantz-all-746466311?ga_submit_new=10%3A1527193113
