I've tracked down some great examples of similar photos to yours with similar scenes, treated in black and white, to help me illustrate to you what I'm talking about.
500px / Photo "Reflection" by Finn Gonschior
Notice the isolation here and simplicity, along with the separated tonality where the darks of the trees are contrasting with the soft grays of the water and the sky.

This shot has nice lines and tonality as well.

This one is cool, with the gradient fog. Notice the reflection is giving a deeper black.
Your first photo is very busy, the reflections are strong, and the sharpening and contrast is harsh and strong. The eye wanders around the frame. The second edit, the contrast looks better. The image looks washed out when you look at it big, there are some processing artificats. Are these both HDR? Has noise reduction been applied?
I believe the issue here is somewhat processing (which you can help), but also the general business of the scene(which you can't really help).
