Cataclysm: dark days ahead is leaking xd

I’ve made this drawing using dip pens and black ink. Adding too much details with this method can cause a part of the drawing to become darker. This happens because the ink always leaves lines with very limited tone variation. Also the fact that I’ve made this drawing rather small doesn’t help. The drawing takes up like 1/6 of an A4 paper

To be honest I didn’t expect this post to blowup so much. Thanks guys!

Thanks!
