Mr Wall! May i just say it's nice to see you in the forum other than stopping a silly fight breaking out
If it were me going into the woods for a shoot i'd lean more towards the sinister side of things. I'd also go for a late afternoon shoot or an early morning shoot so the sun isn't directly over head and more coming in from the side, you've got more chance of getting those shafts of light then.
This is just me but.. I would purchase a few smoke pellets from a joke shop and use maybe half at a time to emphasize the light shafts, you'll get that horror movie effect then. Set one off and let it settle you'll be amazed with the effect!
Good luck with what ever you choose to do and welcome back to the land of togging, it's all down hill from here
