All the above suggestions are excellent. I lived in a thick pine forest for several years and understand the difficulty of finding good compositions. What I did was observe and note scenes that show promise as you walk/drive/run/bike through your local area. Watch and wait for dramatic weather, clouds, fog, snow, frost, nightfall, sunrise/moonrise through the trees, flowers, mushrooms, and combinations of these things. Be persistent and work at it, disappointments will happen and then eventually you will start making good photos. I made a lot of mediocre negatives, and many excellent ones from my time there.
