Wow, I really love the colors...they're just so beautiful and stunning o_o; The perspective you used is really wonderfully too...it really draws your eyes into the picture. And the water line at the bottom is a nice addition...it adds some variety. Really beautiful.
It's incredible how similar the australian and brazilian coasts are! I have been to places that are looks so much like those in your pictures (like this abandoned pier), although I have never been to Australia.
