I think judging in competitions especially in a club environment has a lot of benefits. Open or international competitions are simply next level that challenges you to work and do better, if that's what you want.
We have one of if not the largest clubs in Australia, each month we have a competition,
each months competition the subject can be any one of the subjects on the calendar, example macro, back light, Juxta position, landscape, nature, macro, etc etc
You may enter a set subject listed on the calendar or you can simply put one image into the open competition, or one in set one in open, basically what ever you like.
Each monthly competition has a reputable highly experienced judge that CONSTRUCTIVELY talks about each entry, whats good about it, what it means, what colud be done better, the point is the entrant learns somthing about their own work, as well as seeing hundreds of other images judged again for the good the bad the ugly.
We have seen many novices join our club and after 3 to 4 years being amongst hundreds of talented helpful people see the novice grow in skill and develop their artistic capability to the point where they are winning awards even some in the PSA regulated competitions of America.
Many enjoy the challenge of club competitions, others don't do the competitions, all enjoy the club social aspect and friendship, learning from the large pool of uniquely skilled people.
We have "Get to know your Camera" days every 3 months for the beginners, expert or highly experienced uses of cameras spend 4 hours showing anything and everything about your camera and lens, settings technique etc, we have 3 levels of editing you photo days, for $20 including some lunch like sandwiches tea and coffee you get 6 hours of professional class room like lessons using PS and LR using your own Lap top or you can share one from the club, its done every 3 months, we have a guest speakers each week, people offering photographic trips to Africa, Madagascar, Asia, the Artic etc, we have Nikon, Canon Sony Sigma etc all come along during the year and do presentations with hands on gear on display yes you can touch and feel even the latest gear that you may still be waiting delivery on.
Entering competitions is optional, many elect to enjoy the social aspect and go on the monthly group outings.
Above all, Judges are not always right, one can like the work this month next month a different judge may not.
But i find no one gets fragile about it they simply learn something each month.
Competitions in the main are meant to have you challenge your self, or learn more, and enjoy the growth path, competitions are not for everyone either.
Constructive judging really helps at all levels to make what you do better, if your photos are to a standard of excellence then yes competitions may not be of interest.
