You must have flashed on the first picture which makes the shot a bit too harsh, especially with plants, greens and nature when their colors are vibrant on its own, my personal preference is to go soft and go with natural light. the second is a good overall tone. These two shots are generally cluttered pictures, where the subject, if any, does not shout out. You could try getting creative with your angles, go close, try a macro, shoot from bottom up...
