iggy: looks to me like you know what you want, which is the best start you could have for a project

. i like what you did with the discreet white blur and dropshadow and your improvement on the short blurb and "double d bar & grill". good job!
i think if this was my project id put an end to it here, without more changes, and it seems that's what you're aiming to do yourself, so these suggestions are meant for future projects:
1. if just plain text looks too "dead", try playing around more with opacity levels on the layers and on changing layer modes. for example, a very simple thing that i still use after learning much more sophisticated ones, is to just pull down the opacity on my text layer a tiny wee bit to give a hint of the background under it. very often that is enough to take away the "dead" feeling. it's harder to quickly explain what the different layer modes do and how to best use them for a discreet effect, but simply experimenting will take you a long way.
2. i stroke the outline on a separate layer and put that layer below the actual text layer. that way i still have the sharp outline of the actual text, since the outline stroke tends to soften edges up a bit and that's not always what i want. but playing with layer modes and opacity on the outline stroke is also useful - sometimes i leave the outline stroke on top, blur it a little, set it to "overlay" and delete or mask off anything outside the actual text and adjust opacity til i'm happy. that gives me a very discreet edging on my text that's not quite an outline or a 3d type effect, but a subtle hint of both.
hope that did something for your imagination and good luck with your future ebook covers!
