Thanks all for the feedback.
Regarding #1, it was taken before sunrise, it is a 2 minute exposure, I was hoping for a three colour layer. IMHO, the curved line gives it a bit more dynamic, resulting in a less static image.
As for #2, I took a series of shots, getting my feet wet in the process. This worked the best, as the water was receding, creating these streaks.
Kind regards.
