Some good images there..the first one with the dogs against the sky could have been a tricky one, but the whites on the dog arnt blown out, and you still have a bit detail in the sky, the last one of the stream with the mountains, set it up on a tripod next time, say at approx f11-f22, try it at different long exposures of between 1 second and a couple of minutes and watch the effect on the water, its got the makings of a lovely picture as it is though..
