Another update. Update number 5.
It keeps looking better and better. Thanks for all the feedback so far. They really help.
So far I have been adding lights at trees in the foreground and background. I added some extra lights for the background ground plane and also added some extra detail lights at the foreground.
I changed the camera lens to give it more of a overview. I thought the foreground was too much present in the last version. Now the composition works better.
Also I created some foot prints in the snow just for fun.
Overall I’m pretty happy with it. Maybe I will do something with the Sky. Now its just a simple image from the internet. If I have some time left I will make a matte painting for it.
