I think that the color balance of a lot of these albums are off, it should have an equal (or at least close) amount of dark and light colors. Other wise it looks very cluttered.
The second one especially is an album cover nightmare >.< you can barely see the name and artist. Not trying to be mean, just saying.
I like the TDG one because of the colors and simplicity of it. The colors are equal, and they draw your attention to the birds using color.
Just trying to bring a little discussion into this thread. Also, I'm in a graphics design class, so we're learning about things like this. What makes a good poster, logo, album cover, etc.
