Marsel van Oosten has been named as the overall winner of the 2015 international Travel Photographer of the Year award. The Dutch photographer beat entrants from more than 110 countries to scoop the top prize for two portfolios of work.
The first portfolio includes this picture of cypress trees in the Atchafalaya Basin, Louisiana, USA.
