The teen years is one of the most difficult and unforgettable stage of life. Teenagers, dealing with hormone changes and an ever-complex world, may feel that no one can understand their feelings. So in this Challenge, we'd like to see photos of teenagers - their timeline from puberty to adulthood. What they usually do like going to school, hanging out with friends, their favorite hobbies, doing sports or any activities outdoors, being with their family, their struggles, portraits, etc. Happy Shooting!
