Think of using interesting rocks or boulders that would lead your eyes into the shots, the foregrounds here aren't great, to be blunt. There has to be something a bit more interesting at the water's edge, or if there isn't exclude foreground completely and work on simpler compositions. The other thing for me is I think the editing is overdone, it looks like you've applied HDR effects or 'detail extractor' in Colour Efex, and as Charlie Waite says when it's clear an image has been overmanipulated it destroys the relationship between the image and the viewer. You're questioning all elements instead of enjoying the picture. It's not that they're bad, but work on a more natural look editing wise and search for more interesting foregrounds.
