Thanks so much for your feedback, guys!
You are correct - the dark trees are definitely distracting. I have to work on them when I have some time.
@george: The girl was supposed to look like Little Red Riding Hood so it's an association I wanted to evoke. The other question is if that is the right direction to go. It reduces reality, making it a bit fantasy for the whole image.
@Julian: The trees are in post - I am still fighting with the idea if I should learn to model environments. It goes so much faster in ps! But the modeled environments are just soo awesome and of course you have 100% influence how they look.
@Zdravko: could you please post your project here? It would be great to compare them.
Yet again, thanks for your time!
