One of my favorite pieces! I have looked at it more times than I can count and still, it always amazes me even more!
I love the way you used to color pallet here, the colors are vibrant and portray the forest perfectly! I really like how you dicrease the color count and lean towards more of a darker and blue-ish tone going towards the back of the piece, focusing more on the silhouettes, it looks beautiful!
I also really like the character designs! Your designs are always amazing and this is no exception! (Seeing Borovick again is really really nice, and he really fits well into the enviroment, making some awesome contrast!)
The details of the piece are also amazing! I love all of the stone faces scuttered throughout the piece and the little creatures that live there! (Some of my favorites are the little creatures under the tree (the ones with the green eyes) I really like how mysterious they feel and how they are "spying" / watching the main character from a distance)
I would also like to say that while I do think the piece is awesome, there are some single pixel misplecements scuttered throughout, but nothing really to noticable and it doesn't take away from the majesty of the piece!
I love your work man, you always inspire me!. I hope we get to see even more of your work! (I know there are a lot more pieces posted since this one, but still ... =) ) 
I saw the thumb and immediatly thought "that looks like a Fool piece". Surprise, it is, and its amazing as usual.
Thank you for the kind words.=)
