@rostiger I just insert paper inbetween the pages so they don't smear on each other, that's really it tho :P.
My hand does smudge it up a bit when I draw, but I try to build the shading from the top right frame to the bottom left frame to reduce smearing (I'm a lefty).
@rek Your shading has improved so much! I enjoyed the story too, fantastic work. What do you do to keep the pages from smudging?
