err .. hello s. There are only about 20 trees in total in the back of my image I think..and I have them scattered .. also I use a darker sky but still day and add a light up front ... I am writing a tut on this .. but it will be a while .. would it help to have a "from the top view " In Bryce? I could take a pic of it an upload if you want. If you have any specific questions I would be happy to answer...? I do leave spaces in my tree line .. the trick is to manipulate the haze so it is only at the back so to speak . I learned the trick from the book "Real World Bryce"... Sorry I only just found this thread..
