try and to lower the height of "Johnny Deep", it looks a bit distorted as is.
For the spine, change dvd-logo to the newer one with video written under the "disc".
And for the back, the layout works. But to make it easier to read, it'd personally change the font for the plot to something a bit more in the way of helvetica or similair. Perhaps have a quote or a tagline with the current font?
And under the pic-bar, I'd try and have a pic that'd end above the credits, and just use a texture behind the credits/legals to make it easier to read.
And also, it would make the layout a bit more structured/clear.
Anyway, it looks cool overall. But with some minor tweaking this could be really cool.
Keep it up! (IMG:style_emoticons/default/8834.gif
