Wow, where in Norway? Pretty place!
The angle of the sun has given you some flare, & maybe desaturated your colour a bit. I don't know what direction you were facing, but it might be better with the sun at a different angle, behind the camera more... alternately you could use a lens hood to keep the sun off the lens, or if you haven't got one, just hold your hand or a hat or something, up to shade it (make sure it's not in the photo
)
Did you use a tripod? It might be my monitor, but I'm not sure it's quite tack-sharp. Could be a combination of the wide aperture & slow shutter speed. The 1/45 has made the moving water just a bit misty which is nice, but I'm not quite sure about sharpness otherwise. Or maybe it's that flare softening things.
For a different effect you could try an exposure of a second or so, for some really misty water.
