Just out of curiosity, is it based on the original cover (haven't seen it, but I know of the band MUSE)?
Anyway, the front (outside) looks pretty neat, took a while until I realized it said MUSE in the middle there though. Inside of the front is fine as well, though it could probably do with something more, something that pulls your attention, some more opaque colours.
The back (inside) is decent, and doesn't need a lot of detail considering it is behind the CD, though I can't help but feel the white clouds are too dominant in this one, should be something like with the front- that they are only there to break the chaos. Concluding that this part lacks chaos, pretty much like the inside of the front does as well. Outside (ie back of the cover) looks neat, but I dislike the red spatters, and it looks unfinished compared to the front. I'd add some more detail there and stick with the same style as the front (same colours for the spatter and so on).
As for the CD itself, honestly I don't like it. The black/grey that is there to make a face of the shape does not look very good together with the orange at all. Perhaps red would look better? I mean, the idea is nice, I don't mind it being a silhouette of a face on the CD, but the colours and contrast is wrong, in my opinion.
Keep up the good work - lykke til!
