You could have added some animals, or some fireflies like dudi223 mentioned.

Other than that, I like how it looks.

...

Needs fireflies... some sort of ambient lighting, to make it look more... magic?
Seems too... loneley?

whoa

Lush and bright

Very nice. I'm waiting for Yoda to walk by.

Great for a practice...

... although I think the light green in the water is a bit too vibrant for the lighting. Try using a paler color next time to keep with the mood. As for the misty lighting itself, the large washed out spots near the middle of the picture look a little funny. I like the washed out corner, but my suggestion for the spots is to quickly smudge 'em a bit next time, make them more horizontal and give them more irregular shapes. Also, I think the circles in the bottom left are a bit distracting and I'm not entirely sure what they're supposed to be. Water droplets, maybe? At any rate, consider dialing those back a bit. I like the effect they have in the trees, but they're a bit too concentrated in that one corner, at least in my opinion.
