It is awesome that we have so much knowledge and varying skill
levels of the club members. We can learn so much from each other
and the way each of us see.
Giving and receiving critique is an excellent way to grow and helps
you to see what others see. When you are emotionally attached to an
image, or subject, you get blinders on and don't see the
obvious.
Take critiquing for what it's worth. Don't live or die by it but be
open to it and try and see it from the other's view. Even if
everyone else is wrong, you at least know how everyone else sees it
which probably makes everyone else right ;)
When people think of critique, they usually think of negativity and
fault finding. It doesn’t have to be. Even the worst of images have
some redeeming quality.

Here are some guidelines you can use for critiquing-
Use the Oreo principle Sandwich the things you think could
be improved upon between two positive attributes of the image.
Something like 'I really like the composition of this shot, great
use of the rule of thirds. I think the subject is a little too soft
and there is a soda can in the background. Great color and post
processing.'
Try and think with an open mind It's too easy to get caught
up in our current way of thinking about photography and be less
accepting of all of the different areas. We might be caught up in
artistic type endeavors or we might lean more towards very formal
portraiture and not open to more contemporary styles. This is just
the way people are. Back up and see if you can see what the
photographer saw in their original vision.
If known, take the photographer's skill level into account
We are all at different levels and, unless you decide to stop
progressing, this will always be. What may be a good and
appropriate critique for a professional would neither be good or
appropriate for a beginner. You may not always know what the
photographer's skill level is but, you can sometimes get a feel by
looking through their portfolio. Though refrain from pointing out
there assumed skill level in the critique. For instance, I wouldn't
say 'for a beginner, I think you did great on the lighting'
