Hello every body.
I will appreciate if you critique the following images and let me know your opinions...
Do they lack commercial value and will be low earners

According to my 6 years experience they have low commercial value. I strongly recommend you not to spend much time on that subject. Lets assume SS accepted them, 1-5 lifetime sales for the first image, probably 0 sales for the other two I guess.

Please ask yourself why would buyers buy this image and for what kind of projects they could use it? The light is beautiful in the second and third photos but anyone looking for a nature photo will probably find better ones in the database. So either the topic is oversaturated and the composition is not okay for commercial usage; the color of the water and the white sky is not appealing for me, also in the tree photo it could be a wider composition or you could take a closer one with focusing on the leaves.

The first one seems ok as composition but I would prefer the leaf facing up rather than down.

Try to focus on macro and/or isolated shots if you want/have to continue on this subject. Take leaf and isolate it on white or take macro photos of the plants.
