Nice set of images there, No.1 could do with a horizon straighten and maybe a little bit of the water cropped out but a nice image.
Love the colours in No.3. a bit dark in the foreground.
Not sure about No.2, the sun is blowing out some of the sky, can just about see the colour of the water coming through in the foreground..
Some framing looks a bit OTT but I like the black frame around your set. Just my opinion though.
