Hi guys! I have a foto competion tomorrow, I have choose one foto and describe it in English (4-7sentece), I have no ideas which one to choose of those two:

This is my little sister Mimi and my cousin Tanya. I captured this picture in the park near to my house, it's in Pardubice. This photo symbolizes the peace and the innocence of a child. Two children are giving each other a flower. It shows to us how the childhood could be endlessly beautiful and peaceful with full of hope. I wish a world without the Hate and Violence, I wish to see precious moments like this forever.

This is my father and my sister, in the garden before my house.
One of two photos I will choose to present, but to say the truth I am pondering 3 hours already. I would like to hear some opinion. This pictures were taken by me in 2011.
What do you think about? Which photo shall I choose?
