good start but a couple of things..the cutout on the front, of the characters, have a white line around them.. you can get rid of that by feathering it when you cut it out.
The episode info needs to be a different colour and layed out differently, possibly move the smaller pic up episode information underneath and the pic of the raith (if thats how its spelt) down underneath that to seperate the credits and the episode info.
Barcode...hmm what to do with that barcode...some people like them to be honest I hate them so if you really really really wanna keep it on there then keep it on there but if not I would bin it.
Play with the colours of the character cutouts as well so they blend in better with the background image on the front cover, you could possibly duotone them, see if that works (may not but it doesn't hurt to try it out).
DVD logo could also come off the front you already have that one on the spine and back.
