Design for a tattoo

I want a design for a tattoo. The tattoo is to be a shoulder piece that looks like armour made of Hawaiian tribal designs, but with spikes within the design so it looks a bit like the intertwined branches and thorns of a rose bush but without the flowers. The armour should cover the upper bicep and spread about the chest and shoulder blade coming slightly up the next but not so much that you could see it above a t-shirt line
