G'day Kenny,
Judging by the shots you already have good skills, framing's good with the horizon on the top third etc. and interestign parts in the bottom two corners being the thirds sort of thing, the lack of clouds and interesting shapes in the sky makes it harder so I think to improve that shot much unless from a different angle maybe?
Just rambling trying to offer suggestions or ideas it's all good fun
Maybe if you got down lower and tried to include something to catch the eye closer in the foreground, maybe a flower/plant or something, or take the shot from down on the shore you could get some great angles with the rocks in the water as a foreground interest etc... The polariser does a great job on water huh.
I think the same sorts of things for the second one and the horizon's a bit squashed up the top so it catches me a bit, and I assume that due to it being right up the top it seems to have curved the horizon, easily fixed in PP... The horizon police'll getcha
Try a few different crops of the same images, and see the sorts of diffferences and se if that helps, worth a try
Getting the exposure right in these would have been tricky as they look as though they were taken maybe in the middle'ish of the day(?) so that makes the lighting harder, long shadows and late light colors do wonders for these sorts of shots...
Just rambling hope it's helpful...
