I mostly do presketch ideas.A presketch is a drawing with rough lines and little to no details.In collaboration with the customer I try to capture the essence of the meaning of the tatoo to help the tattoo artist have a blueprint for his work.Symbols and logos,no letters and 2D anime or comicbook characters with some details.No color in my presketches.You tell me what you want (if you have some references the better) I draw it on paper.Also here keep it simple.
