I really like this. Kind of an odd/ugly design for the album though what with the lone floating image to the left. Before I saw the reference I just thought you were being lazy and didn't pixel it big enough and just filled the image to get by the rule. But nope. So good job. :B

great! your best work so far I think.

bigger could be better.

I like this a lot!  Great job!

oh what a fantastic cover + cover pixel adaptation! Great choice!

Very good, but my votes will go to re-envisioned covers. 

I just did. Though it DOES look very suspicious, it really seems to have been done by hand.
The reason I was suspicious is that it is so different from your earlier pieces.

...All done by hand and not traced or colour reduced etc...D:

If I really have to I'll make a WIP animation...but if you check the challenge thread I've posted a few progress (no pun intended :P) stages...and if you really  want you can try resizing and colour reducing the original, then comparing the results.

sorry, it look like a size + color reducing of the reference to me, especially because of the white BG and the "progress".
But I don't really have a doubt about the authenticity, you made lot of pixels, so I think you're enough mature to make it by hand

good job, I like the preview

PS : AW sorry, I didn't thought that was for the challenge...so, no problem for the "progress" and the background :)

Cool! gj
