I find the plants and clouds too blurry. Did you try to paint over them? They would look better crisp or a bit clearer,
since the contrast between the background and the character is too obvious.
Also, the grass in front of the character isn't a too good addition. You can just say the character is in front of
everything, or you can add some bigger plants/grass in front of her, if you want to say she's lost in the jungle ^_^'
I suggest making the plants of a lighter color, since you can't really distinguish the background.
Except for the blurriness, the moon seems to be ok.
A good thing would be adding some textures to the girl's cross :) That way it wouldn't look like blank space.
