We like this entry, but we don't like the all the shadows and gradients in the blue ball. We'd prefer more of a vector flat look. We also don't like the shadow.
entry 68 has an excellent font. we are concerned the artwork looks a little too much like the old cingular logo (http://designcrack.com/v2/wp-content/uploads/2007/05/hotdoll-cingular.jpg), so perhaps you can tweak that a bit. Also, can you make the text larger so that its vertical size is closer to that of the artwork.
Can you update entry 100; we like the artwork, but can you make it more of a complete circle/sphere so its not as much like a "u". You might have to move "life" down to its own line also
