Wow! You managed to shoot something so simple and put so many feeling in it. The cropping is awesome, I think it's a good choice to put the leaf in the centre, it makes the feeling of being lost coming out so much better. Great job!
And why are you feeling "at lost"? ...lost yet you still able to catch this simple yet extraordinary scene... has an abstract feel, the pavement's color is just natural but very attractive.... also, i felt loneliness here. Great job, Pia! :)
