both shots are a good stop underexposed to my eye.
shot 1 - If the kayaks are the main subject, why include all that darkness in the shadows around them. I see 2 kids at the end of the shot, but they too are underexposed and less interesting than the kayaks themselves.
Personally I would have cropped much tighter and the underexposure would have been less apparent.
shot 2 - The underexposed man is not helping in shot 2, he is a distraction to my eye - not sure why you included him.
Hope that may help
