Awww,... these guys were too gentle. Now for some blood letting. Just kidding. My opinions may differ from theirs (and yours), but remember they are just opinions.
From what I can see behind all those trees, there was a nice sunset, a beautiful water, reflections,... enough to make really nice shots. In the first one, using the trees on the sides to frame the lake are fine and provide a depth to the picture, but the tree (and bare bush) in the center take over and become the focus of the picture. The water and sunset take a back seat. Had the tree and bush been really unusual or pretty, then they could have carried the photo without the sunset. Such was not the case.
In the second shot, none of the trees is particularly notable, and the tops are chopped off. The result is that they just create a barrier to block a beautiful scenic shot. Whatever you put in the middle of your picture, especially if it is as close as those trees, becomes the subject of the picture. With the water and sunset, I doubt if that was your intention.
If you look to the left of the second picture there is a little cove with reeds and a rock. Had you moved to the left to find a clear area you could have used the trees to frame the picture (similar to the first one) and used the edge of the water, reeds, etc. in the foreground and had a clear shot of the bay, sunset and reflection. I think it would have been beautiful.
The main thing is to visualize the scene as you want it to come out, before you take the picture. Keep shooting and posting,... and soon we will just be saying, "Wow, that's beautiful".
