Concept Art for a Recent Tattoo

I haven't posted anything in a while... just been busy tattooing and working and traveling and so on. So I figured I'd post this concept sketch I did a while back for a tattoo I was designing. I didn't end up doing this exact tattoo but a similar one based on the same theme. The client wanted a design that incorporated a "City on a Hill", a religious reference. I thought a cool retro travel poster theme would be in order. I still dig this design even tho we went with another approach, and thought it worthy of my little corner of the interwebs.
