1920 x 1200 version is best yo. Or any higher resolution, see below.

I've had my eye on this scan for a while. At first I wasn't sure of what to do with it - just that I had to do something with it - but, after getting tired of it sitting in my Future projects folder, I decided to simply vector it as-is. So I opened it up, inverted the color scheme so I could see the parts I wanted to work with, and finished this in around 3 days, with about 2 hours of work/day. It took so long mainly because I kept moving shapes around and selecting all those tiny specks was a pain XD

98% of this is Freeform Pen Tool, with the bulk of the bigger waves done with the regular Pen Tool. Using the regular one all the time would have interfered with the look, and I wanted something more unpolished and slightly "chaotic", so smooth curves were a no-go.

At first, I wasn't going to extend the scan since I wasn't too fond of the lumps of shading on the left (in the original scan), but after breaking them down into several smaller ripples they turned out decent so I kept them. Added a texture from Pendle Stock at the end just for variety's sake, but I admit the textureless version (uploaded here) is my favorite c:
