I bought these cheap Sharpie Ultra Fine Point Permanent Markers and got the bright idea to try creating a lineart of a sketch with them. Though they bleed like sunavagun's, I was surprised by the outcome! Colored it with Prisma's....
Really just drew the first thing to come to mind, but this is the first time I actually had some inspiration to draw armor in a while, so I went with it.
Shells and coral, a beach/sea/ocean kind of theme.
Hope you enjoy.
