Tattoo designs

This one here is what I have designed for Kevin, The main turtle and shell is to represent security. The triple twist going through the middle represents two lives twisting into one, and the two turtles within the shell represent Guardian/Protector and Family. 

This one is what I design for Simon, its to go around the top of his forearm and sit above the outline of New Zealand, his existing tattoo. He was wanting something Kiwiana'ish but I was trying to keep away from chliche Kiwiana. Just a rough sketch for now.

Feedback welcome.
