Feedback on Mock up- Digipak

After showing my teacher my mock up she gave me her feedback on what she generally thought was good and what could look better also where to a put a few missing informations.
On my front cover, she didn't really feel that I should have the image like that, suggested one would be better off but I explained that the actual image being one was too big and when placing it on the template it looked squashed when I tried to fit it in so she thought that the image I used inside would be way better if it was placed as the front cover and the original one I had outside to be inside the digipak. I liked that idea so I made some changes.
My teacher also noticed that I hadn't included none of the copyright information & catalogue number.
With the inside of my digipak, she thought I could include some acknowledgements since it kind of looked plain.
In my mock up you can see the back cover having some sort of design round it but seeing one person in my group already having something like that I've been trying to think of other stuff that could look just as good to place because right now its looking very detailed but plain.
Another thing my teacher had told us was to make sure our titles could stand out from afar, so selecting the right font would be ideal.
Listening to everything she had said in that lesson I decided to do another digipak but this time all on Photoshop.

And this is the inside.. but I'm planning to keep the same design of the CD on my mock up in the final one.

As you can see it is looking quite plain :(... I need to change this.
