I initially wanted to draw a mandala but after outlining the big circles, I thought "why not add some texture?" and there you go. Experimenting with different shapes and shades always pays off.
Ink & graphite doodles/sketches, (this time more graphite than ink.)
A5 size ruled notepad paper.
This started out like other doodles of mine, but quickly morphed into something a bit more deliberate and complicated.
