The main theme of this half sleeve and pec tattoo prepared for Damian using mainly Samoan elements is being a warrior and fighting spirit and resilience (the warrior, spearheads, octopus tentacles, and centipedes), as well as the importance of family and friendsip (flax leaves, braid, manulua, chasing birds, people).

The row of spearheads on top, flanked by octopus tentacles and with a row of birds below them, represents his voyage in life, from past to future, faced with strength, adaptability and an open mind which gave him have a higher perspective upon the world.

Many challenges were faced along this voyage (the paths of Kamehameha), overcome with detemination, strength and tenacity until reaching prosperity (coconut leaves, fish, trochus shells).
