Incidentally, before I started on the LZ Character Advancement pamphlet, I was already dissatisfied with the cover image I did for the gear pamphlet. It looks very cluttered, like the various props (anvil, hammer, dice, etc.) are there without reason, instead of being poured out of the bag, which is the image I had in mind.
I kind of didn't like the other cover images I did for the LZ pamphlets, either. I liked the basic concept of the piece of paper being broken through. Just didn't like the scenes I'd arranged.
So I did the XP pamphlet cover in a more minimal style, halfway between a normal illustration and an icon or logo. And I redid the other cover images, too.
I think I might stick with this style.
