That's obviously just in pencil, but im gonna get a brush and paint it metalic blue shortly. I just want a variety of opinions about it - too big/ too small curves? About the right amount? Look "uniform" ish? I was planning on covering the whole side but the little bit looks better imo. As for the actual design ive been doing it years - i generally cover the inside of folders with biro and tipex (ill get a pic of my GCSE history folder later), all the lines flow into points, typically the point are a different colour to the interpoint connections but i dont think i can pull that off with paint.
