Captured this during a bushwalk this morning in the Blue Mountains west of Sydney. A quite common reptile growing to about 18 inches. Lives near water as the name suggests. Almost full frame with a 30D, 300/4 IS and 1.4x. Flash was 430EX at -2/3.
Excellent pose and detail Akos. I would add some canvas above and maybe trim some off the right side. If you are OK with cloning, you could try to remove the square catchlight in his eye. I like the way you emphasized the scales and the eye. Good job.
