I do really like it but the only thing is that I didn't notice the lion at first I just registered the wolf, though I think I understand why you put them that way, it's a really cool concept and I like the colors, so I don't know if that's really helpful but yeah
Okay, a suggestion on the colors: the dark grey lions on light grey fancystuff doesn't quite look right, might want to go for another color entirely (gold?) for balance. Also, you might want to make the "You Win..." a bit larger/more of a focus, I only noticed it as an after thought.
