I *really* like this one (#47). The font is my personal favorite, the colors are my favorite, and the iconic logo is nice. However, the fact that it doesn't have a tree is a deal killer. Also, it needs to look like a koa tree. See feedback on the other top entries for more detail.
This would be my top pick if not for the absence of a tree.
#63 we like very much, but the hills look a little rough, even hand-drawn. (of course they were!) I'm not sure - I guess I'm looking for something different in the hills here.
Wow, thanks for all the work. Could you do a quick revision of #82 which has a little green shading in the hill? The same sort of shading you have in #83... Or use brown shading there if you feel that looks better. I feel like the balance is off a little bit, and that the hill needs a little more definition. I like 83, but I feel like all of the brown makes it a little dark/heavy. Looking great though!!!
