Tattoo for a friend

my friend who's serving in the military in israel right now for a few months will be back home in ontario in march, he's planning to visit me in april we hope. anyway he wanted me to design a tattoo for him involving a horse & fish (seperately or combined), and wanted it to be tribal. this is one of the designs i came up with, its based on celtic cave art from 1st century, i used various references to combine the animals. i dunno if he picked it yet, but i wanted to show it anyway. if not i have more ideas for his tattoo.

original fish & horse (seperate) copyright the celts, even tho they're long dead and gone,lol
