I agree, the fan made one posted in the forums, and here, is the best I've seen (aside from the non-original logo and monster on the back since I dislike the spoiler). I know in America cliqué action games sell but the design almost makes it look cheap, but that's just my opinion. Either way I hope the game sells well once it's being sold in stores!
The fan-made Amnesia DVD box art is quite good but it needs the official font design and Agrippa could be too much of a spoiler. Also, what's with the rating? 'Mild Lyrics'? Last time I checked, Amnesia wasn't a musical. Also, there really isn't Intense Violence, maybe Disturbing Imagery would work better.
And its useless, he doesn't have a printable version.
