Looks very neat so far mate!
I only feel the 13th episode feels rather off in terms of placing. I'd personally put 7 ep's in the first row and then 6 in the second (right) row.
And you're also using the "old" dvd-logo. The one preferred is the one with "video" written under the disc.
Perhaps a picture on the spines, or you want to keep that clean? (IMG:style_emoticons/default/8834.gif
Anyway, nice work so far!
