Exposure is fine on both images, but the composition seems a little lacking; nothing concrete I can put my finger on, I guess just a lack of something. I think #1 would have benefitted from a little more of the building to the left showing. As well the boardwalk tends to take the eye right across the bottom of the image and out, always try and use lines like this to lead to the middle of the image. #2 woud be helped by the removal of the rental sign in the middle of the image.
