EOS concept
I thought this concept really captures the idea of your product. It features an Ent, complete with rolled up walking stick (they are known as the shepherds of the trees.) The colors are organic and neutral, the fonts are whimsical and interesting, and over all I think it has a very calm, relaxed, and mellow vibe to it. I can make revisions if you are seriously interested.
