First one is a close-up of a palm tree leaf. I think the sun and shadows give a nice pattern. I think the sunshine changed the green colours in to a bit more pleasant green :)
I know this grass may not be qualified as an abstract photograph in stricter terms. But the the combination of few grass and the pattern it creates may be an interesting formation.
The tip of this bush surely creates an abstract image
The dried tip of the flowers :)
Lets see anyone likes this :)
