I think I'll do a "layout primer" just for the heck of it.
Some comments on the PDF, although we're rapidly approaching "off topic":
- I'm with Cergorach on most points (make that: all

).
- The column width on the first page is due to the third column, isn't it? I'd say this third column, as original as it seems, isn't that good an idea after all, or at least it's not that well done. Don't do it - put those information (together with copyright remarks) on the bottom of the page.
- Lines should be 0.5 points thick, unless there's a reason for the lines to be thicker (and I don't think that's the case here)
- I like the fact that there's some room before the first line of each paragraph. However, it's too much room. Half as much would suffice.
- On the same topic: don't leave that room for the first paragraph after a headline
or after a list (for example: after the spell parameters). That doesn't look too good.
- On the same topic yet again: you don't use that room with the feats. Any particular reason?
- Personally, I don't like your headline font. It can't be read that well. But seeing that we're talking "role-playing game" here, this might not be what you're aiming for - some of the "big guys" do it your way too

- There's a thing called "baseline grid". Call me old-fashioned, but I rather like it. That way the lines of your main text (in every column, on every page) will be on equal height.
- That's all for now - anything more would likely be a matter of personal taste. But do include a page number
A new forum for similar questions would be useful I think. Although there's the problem that only people seeking help would visit it.

Another option is to use your layout design, but have Jabberwocky (or the equivalent) do the text for you so the text is just garbage random characters.
That's called "Blindtext" in german. Yes, the verbatim translation is "blind text".

Not sure what the actual word is, though.
