Haiku 1 - Apples

[dukealien]

Colour-blind people
picking apples in harvest
want sweet and crunch; sour

In intensive critique, I'd class this as senryu rather than haiku - there is a seasonal reference, but the poem deals with people's foibles rather than nature.

The first line sets the scene well enough, but perhaps "people" could be replaced with a more specific word to add  depth - "women," perhaps.

Second line:  choosing, not recovering windfalls (which would more or less automatically be at least ripe).  Since senryu doesn't require a seasonal reference, this line could fill in the picture - 'from ladders" instead of 'in harvest," for example.  Or choke up on the bat a bit with "want sweetness."

With sweetness covered in the second line, the abrupt turn can be enhanced - "and crunch:  bitterness."

Not intended as a rewrite, only examples of possible improvements.  Accepting that it's senryu, words which also apply to emotions become useful.

(Above without looking at other critiques - may be repetitive.)
