Darkness may mean a lot of things, in a lot of ways (so i just used some symbolisms in this artwork). Darkness may be related to our feelings of emptiness, of loneliness, sorrow, grief over losing someone special, failures, and many other things. We may not be able to completely go away from darkness (just like being under the dark sky), but the way to be "out" of it is the ability to continue life (footsteps), be open for new experiences and new opportunities (an opened door), find hope (flowers) and learn that there is something beautiful waiting for you no matter how empty, how dark, or ugly you feel your life is(just like a butterfly who once had been a caterpillar). Being out of darkness is also knowing who your true friends were, those that stay with you no matter what (just like the stars on a night sky). It may also mean making each moment special, though they may seem just ordinary, and to feel that you have a purpose to this world. =)
