THe shot is beautiful and the colors quite warm and inviting. It immediately seems to say sit back, relax, enjoy a glass of your favorite beverage an dlet it all hang out.
From a composition standpoint some might suggest moving the horizon to suit the rule of thirds. If you haven't heard of it befroe it's a general composition rule suggesting that the focal point of the shot should lie on a plane one-third from the borders. This enhances the impact of the photo. Personally in this case I think the horizon being almost in the middle works because the sun is near the thirds mark.
Cheers and good work...
