Had to render and draw 5 skulls for my life drawing course my winter quarter freshman year, and this was one of the best line drawings in my sketchbook.
haha I did draw it pretty quickly since it's about 5x5in. My friend said it took me only 10-20minutes to render? Idk but it was a lot of fun to draw, I got a whole sketchbook full of life drawing sketches.
