Album Cover Template

I have started making the template for my album cover. This will include the back cover and the front cover with is attached to the booklet.
I have put some screenshots below to show how I have made the template and what they look like so far:

Dimensions
12cm x12cm (per window)

This is the front cover with the booklet. I have divided it up into 5 equal windows and this will be double sided so in total I will have 10 windows to fill up. One of the windows will be the front cover and another of the windows will be the back of the booklet. I have thought of some ideas for this which could be continuing the theme of inside the booklet with a background and then text on top, or alternatively I could do a shot of the band with a similar background as the rest of the booklet.

Dimensions
15cm x 12cm (middle section)
0.6cm x 12cm (spine on both sides)

This is the back cover which will be double sided as well. One side will be for the track list and the other will be the side that will be seen under the CD. As you can see, there I have made 2 dividers which will be for where the two spines are either side of the CD case. These will have the artists name on them and possibly the album name as well. 

For the back cover as well as the track list I will have to think about other features I should include. I have looked at a few back covers of a similar genre to my artist and they seem to include similar features (as well as track list) such as the producers, their record label, artists website, record labels website, copyrights and barcode.
