Hello Haiku

This is my first attempt at Haiku.

I've followed the 5-7-5 syllables rule religiously; and I have tried to take a snapshot of nature with each set of three lines, complete with two distinct ideas in each set.

There's a big chance that they aren't very good. If you agree, don't hesitate to let me know. In the oft chance that you do like them, don't hesitate to let me know either.

palms in the wind sway
a twig snaps below my feet
my insides crumble

yon dusty highway
water droplets on the screen
parched soil all around

the dunes are yellow
lone beauty of a cactus
pricks the human soul

the sparkling white snow
rests the sun behind the peaks
the dawn rushes in

the calm of the green
the predator stalks the prey
the deer grazes on

crashing of the waves
a crab walks sideways in sand
all marks washed away
