One thing I want to point out is that these recent sheets are all hand-written, obviously, and prone to error. Many of the details are invented right on the page as I go along. Often I will have a white space that seems empty so it gets filled with a bit of sidebar graphics or, in some cases, an impromptu table or class ability that wasn't planned.
In other cases I spell something wrong, in ink. I detest using white out or anything like that (though I sometimes have to do it). If I can, I will roll with a mis-spelled word and spin it into a "deliberate" element of the sheet. And that's how we end up with the class ability called "Flyng" instead of "Flying Death" as it was supposed to be.
