Hi mossyoak! What pretty scenery! #2 is my favorite shot out of the bunch. Your composition the best in it I feel. The highlights in the sky are very blown-out looking though. Notice how there are no details in the clouds. I assume you are using a point & shoot camera? Its hard to get perfectly exposed skies with those cameras. A SLR camera allows you some room to adjust for bright skies and will also provide better photo quality as well.
#1 isn't bad, but it lacks a subject or point of interest in the shot. Your eye just jumps from ice to wall to trees to foreground and has no place to settle.
#3's highlights are really blown out and have no detail at all, which again is probably the camera. Your angle is a little strained as well. I think getting all of the bridge in there would have been better, as well as the bottom of the log. Its looks maybe a little crooked too. I might have tried a horizontal shot from a little more ways back and saw how that worked. Could probably use a little boost in color as well, but that can be easily adjusted in PP.
Anyway I hope that helps.
