I have two.
My first one was the Soufly symbol on my right forearm, not to represent the band, but more so the meaning behind the name and meaning of the symbol.
My second tattoo is a Viking head up on my left bicep. Same one from the Ensiferum hoodie, but modified a bit.
Going to be getting a Thor's Hammer next, not sure where to put it though, either middle of upper back or somewhere on left arm, maybe even leg.
