Picture #1 is by far my favorite. Nicely composed and perfectly exposed. A little more Bokeh would have made it really pop. Picture 2 & 4 are similar in subject matter, both suffer from being way too busy, and over exposed. Just nothing to hold ones interest Picture # 3 is a nice well composed waterway picture that is properly exposed. I would place the sky at just 1/3 and the water/jungle at 2/3.
