The new 2013 logo is unbalanced & dull.
1) First it's extremely unbalanced, all the eye popping color, depth, & detail is in the tail with nearly no highlights on the left side of the logo.
2) The fur on the end of the tail is 3D, slightly wrapping itself around the globe. Why? Why simplify the whole logo and leave the tail with the same awful complexities as the previous 09-13 logo? The tails in the 04-05 and 05-09 are near perfection and more simple. The newer tails add unnecessary detail yet they were kept.
3) It's inconsistently flat. Usually flat coincides with simple, but the logo's complex outlines have actually been exaggerated while the coloring has been flattened and simplified. The fox's head and torso on the other hand were nicely simplified (aside from the little hairs added all over).
4) It's dull. What was once planet earth is now a dull blue ball with coffee stains.
5) The gradient of orange to yellow is too hard. The entire fox is orange then sharply turns to yellow after the tail starts. The gradient change in the 04-05 version is perfect. The new logo's gradient is harsh and too distracting.
6) Micro-details were added. Why? I thought this was about simplifying? Look at the fox's fur on it's back. There's little tiny hairs that have been added that weren't there in the 04-05 and 05-09 version. There's no reason for those to be there. When the logo is shrunk and viewed at it's normal size they won't even be visible, why not just remove them altogether. In fact the ears have added hairs as well.
It's easily salvageable and the designer was on the right track:
Just bright up planet earth, contrast the continents from the ocean more, remove the 3D-ness of the fox's tail, further simplify or remove the tail's inner fur spikes, and soften the gradient of orange to yellow that runs across the fox's body and get rid of those annoying hairs that one can only see when zoomed in 400%.
