Trees are very good subjects of photography, especially those deciduous trees that change their leaves to beautiful shades of reds, oranges and yellows. However, those kind of trees are not very common in our tropical country; we have evergreen trees instead. My favorite among all is acacia because of its wonderful boughs that intertwine in an aesthetic way.
I also adore the forget-me-not powder blue color of the sky, especially when there are fine wisps of cirrus clouds or fluffy cotton-like cumulus clouds that seem to indicate movement. So sometimes, I include it in my photos depending on the cloud formation and the blueness of the sky.
