You are your own best critic!
Personally, I think sunsets need to have something really special to lift them out of the "mmm, that's pretty" category - and this one doesn't - at least for me.
The view of the lake through the trees is nice: but for an image to really pop, it requires some strong visual elements (shape, colour, balance or whatever) to draw it together. Multiple trees of mixed species - as you have here - are often very difficult to pull together as a harmonious whole: you need to find some pattern or flow in them that leads the eye round the frame in a pleasing way.
