Dhana, yes the biggest question here is what type of gear do you have? Lighting a night exterior can be quite simple with a couple day 5600K back lights and some fill light either bounced with a big 12X or supplemented with a few soft sources like Kino's or equivalent. The nice thing about your image of the forest is that the tree clusters are spread out enough for light shafts to fall through the gaps since the branches aren't full up with leaves quite yet. (Get away with using a smaller light! = less money spent. ) If you keep your shots tight, this will help a lot. Night lighting gets expensive really quick for wide shots that need deep background lighting.
