Thanks Nivek for taking the time to reply - it's funny how you don't see the obvious things until the tattoos finished - your right though the panther looks a little skinny.

There's purple, blue, grey and white in with the black of the panther - I've found that the formula 51 grey "disappears" into the skin like the white, but comes back in a day or 2, I've asked the guy to call back into the shop in a few days anyway for me to look at it.

I'll get some more photos then.
