I have to agree with Rolo'sMummy.... I like #4.... the others(IMHO) lack a point of interest or are out of focus.... #3 does have a point of interest and the composition is good and some people like this kind of picture but nature tends to be my kind of photography...#2 would have been my choice if there was a point of interest, such as a kayak or canoe... maybe a 'POP' of color, as a orange kayak... of course, with a touch of Photoshop they ALL can be frameable
still they all are good pics...... well done!
