Looks cool! If you don't mind a little constructive criticism (if you do, just skip over this), but I think you may want to add a little more contrast between colors. Right now, the whole grey/light brown/dark green really blend into each other. Perhaps use a little deeper brown for the wood, or a brighter green for the moss. Just a suggestion.
I missed this thread so far; I have no idea how.. (actually I know, I don't read this subforum enough; I still have to compliment you about Aerie.. )
This Age has some serious potential.. I really like the concept and the current look (I love 'vegetal' Ages). I'm curious to see where you will take it.
