They are pleasing as wall paper. But, they each need a more specific subject, if even just a parakeet sitting on the bush. They do have nice technique and good exposure control, but emotionally have little stopping power.
I sort of have to agree.
These are nice shots but they do lack impact.
As one who also photographs rainforest this issue of not being able to see the forest for the trees is a tricky one to overcome.
It is even more acute when one is in the midst of the forest.
Nonetheless it can be be overcome.
A possible solution is to select out specific elements as a highlight with the rest of the forest as the background.
