I had a question for those of you printing these out:
What kind of paper are you using, and/or are you doing it from home on a fancy printer? Or should I be skimming past thread pages for that information?
@tintagel: The more I look it over, the more I keep having this thought come to mind: I like the light text on dark background, really I do. I won't claim expertise on printing exertion, though (see above question... :>) One thing that really keeps going through my mind is the possibility of a kind of "watermark" in the cardname section describing the timing of the power (something you probably could do in Photoshop?) What I mean is a faint "At-Will" behind the "Eldritch Blast", as an example. If I had Photoshop, and experience with it more importantly, I'd do it myself to see if it clashed with the Power Name, but it's a thought that keeps intruding whenever I look at your attachment. <3
@randolph: I like the included art, but that seems a prime candidate for being more of a background instead of a seeming limiter on text space, as your printed out versions seem to behave. For instance, and this is just my editor side speaking here, I would leave a definitive space between the "Effect" sections and the "how-to-use" portions of each. In other words, Cause Fear's text would intrude into the artwork due to the line break. On the other hand, the art could be "stretched" to be a background of sorts for the entire card. That's what comes to mind when I look over your printouts: don't let the artwork limit the size or you'll really be in a bind.

I'd also personally make the bottom part of the card exclusively for the Class information ("Cleric Attack" etc.) and move the power source to just below the Encounter text, centering it in bold in the card text box.
... I really wish I could draw pretty pictures to explain what I mean, rather than resort to text. :<
