I see the new K! Fonts are funny. I love the way Canyon looks, but there's something about the way Eureka looks that reminds me of an older person's shaky handwriting (no offense against older people and their handwriting!) And its a bit hard to read the word Eureka.
But I love the Studios font. And I love your concept here.
I think the green tree is more of an image that is Eureka Canyonish. But i love the colors and wider shape of #39. I know, I'm not helping much here. Just talking out loud....
