Welcome aboard Robert!
I will try and give you my honest opinion and thoughts on your picture I hope you find it useful.
Sunsets and sunrises are common subjects in photography, but that doesn't mean not to avoid doing them, each and everyone one has a personal meaning to the photographer. You are entitled to come back to it and enjoy it as a memory. I don't know if the lake is near your place or a holiday destination but the fact that you were there can be satisfying on its own sake.
I applaud your decisions to choose ISO 80 and to shoot this picture vertically, You seem to have used the path of light into the frame.
You have let the water create a diagonal shape in the picture which makes it interesting as they give a sense of rough texture which contrasts the even fine texture of the sand. These are good starting points and it's really nice you have noticed them. Actually, you could do a new frame with just these two elements, no sun, no trees in the background
I do not like the inclusion of the bright sun in the frame,- it's too dominant and almost non usable, the shining through the waves seems sufficient to me- while the inclusion of a part of the clouds adds a hint of the fall coming and the rain. Less is more, be minimalist.
The picture could also work in black and white, you have strong elements to turn black - like the background trees- and elements to go white -like the shining of the light on the water-.
It's good to be minimalist but remember you can be minimalist even if you add things in a picture. A footprint on the bottom of the frame, near where the shining ends, could imply (due to the human's absence) a human presence, milliseconds before you fire the shutter. In the lack of anyone else to make them for you, make these footprints yourself. Have fun. Try creating stories with your pictures. Be imaginative.
