another update. I have worked on the wall, making it less straigt and perfect. Followed Walli's suggestion to let the sand pile up near the wall and at the tree and under the bench, added a pathway to the bench or white, flat pebbles.
Added another bush species. Resized the bench, making it a little bit smaller. Added displacement to the palm bark.
And probably I have made the sand ripples too big... hmm.
Thanks,
Frank
