How to design a maori shoulder tattoo: Step four

I completely filled the tattoo sketch with maori, tribal and polynesian style shapes.
The design is finished in pencil and at this stage it's not very clean and tight.

Here's the combined picture of both sides of the tattoo fitting perfectly and seamless:

Now I use a quality marker with a tip of 2mm, and start tracing the entire design.
After a few years of practise a got quite a steady hand for drawing straight sharp lines.

Tomorrow I post the entire Maori shoulder tattoo design.

Kind regards, Mark Storm
