Looks great, you did the background for a nice picture, now where is the foreground 
This reminds me of an old animated movie with a giant robot and a few kids ( kid? ), but I forgot the name.
You mean,
The Iron Giant, maybe?
Thanks for the praise, guys, feels great to hear that the atmosphere is what people enjoy.
The atmosphere is what really brought me in, yes. This piece tells a story like nothing else (although I'm actually one of those people that enjoys seeing what ACTUALLY happens rather than what could happen, I don't like everlasting cliffhangers) the soothing and calming greens put my body at a state of rest and comfort, they let my mind wander without distraction into the unknown depths of nature. That's how it makes me feel.
I love, love, the little sparkles you added in the rays of light. Little things like this really improve a piece like this a whole lot.
I agree with Nystre and yourself, and love the girl, AND her style, but in terms of atmosphere only, she really does break it.
She's having some sort of kitschy picnic in some sacred forest, what's up with that anyway.
I feel like this would be a great part of an intro. Cute little girl, without a care in the world, wanting to have a little tea party with her stuffed animal(s) (make!) and wanders into the forest to find a nice place. She probably doesn't even realize what she's sitting on/in front of, or just has no care. Maybe she just doesn't know. Then, who knows what will happen next, she'll probably accidentally awaken the robot, maybe it will try to exterminate her, but they end up becoming the best of friends.. ! I'm pretty sure I've seen/read that somewhere before, though..
I agree with EyeCraft on everything but the rocks. If they were any more boosted up, they'll compete with the robot for attention. There's contrast in sharp lines and angles, and softness and blobiness. I think it's in perfect harmony right now. Btw, I have the same dilemma as you when it comes to rocks.
Sorry.. Wasn't much of a crit! This piece is excellent.
