Yes I have to admit the variations of dark into light and vice versa are hard for me to read and the print is smaller too. Just doesn't flow as well. This is where I think "less is more" and "more is less" from my art student days.
Way too dark for me, too.
I think it looks great. I agree that dark over dark can be a bit hard on some people.
YES, I do have a hard time reading it, and I'm not that old.
