I like the H and K an Z in the font so I used it for those letters tbh. The c4d was added last because it went well with the flow I used by creating the glow lines, the sig was too flat and not enough kick without the little extra.

Like I said had nothing like this in my mind so this was a pure "chizzle out of marble" thing :P
I am happy with my results to turn it over as a gift ^^
