Berserk

Wow, what an effort! This was done completely in biro pen - no pencil outline, no nothing, so there had to be absolutely no mistakes.
And I was originally just practicing sketching Guts' face

Oh, it was about halfway through that I realized I was drawing in blue rather than black
Ah well.

I used a reference for this - again, this was supposed to just be a quick sketch for practice which evolved into something more.
