Estonian artist Alika goes for a spine-tingling walk on the roof of the enormous Tallinn TV Tower, even summoning the courage to dangle her feet over the edge. Note from the shoot: Alika had never walked on top of the TV tower before. She wasn't nervous at all - she loved it at the top of the tower and couldn't help herself from dancing around and sitting right on the edge, watching the world go by. She was of course attached to a safety line at all times!
