I have two Russian students, Svetlana and Tatiana, who are addicted to their mobile phones. Yesterday during our evening break most of the students walked with me to the beach to watch the sunset. At one point while we were enjoying the beautiful sunset and the ocean, Svetlana and Tatiana both put their heads down and I took a picture of them while they were using their mobile phones. 
I want to send them a copy of this picture and write "Hello Svetlana and Tatiana, the world is out here!"
Would the following be correct:
Привет Светлана и Татьяна, Мир здесь!
Заранее спасибо!
