Yay:
I like the darkness, the wood-theme, the colors and low contrast.
Nay:
The low contrast is just a little bit too low. The active tab looks almost just like inactive tabs.

As my as I love jet black backgrounds and dark themes it does need a contrast that won't jar the eyes. The muted wood tones are perfect for my tastes and I love nature and woodworking. I shop loads of themes and this one fits me.Danke.
