Start with the cylindrical object positioned on the upper part of the tattoo (e.g., upper forearm or bicep). From the cylinder, have a single clean line emerge, mimicking your sketch’s path, curving gracefully around the arm. As the line descends and curves, it should naturally transition into the golden spiral, just like the second image. The spiral should be prominent, with the classic Fibonacci/golden ratio proportions. Inside the spiral, you can include wave elements or keep it minimal, depending on your style preference.
