I go through the gallery when I can and checkout images that catch my attention for one reason or another.  There have been times when I've left "constructive" feedback due to things I've noticed.

For example, on one image (of an artistic nude), the majority of the shot was well done, except there was a noticeable white area in the upper corner of the image that seemed out of place and was really distracting to me. Especially, since the studio backdrop used consisted mostly of crushed red (velvet)material.  Every other comment on this photo totally ignored this obvious compositional mistake.  Hmm... wonder WHY?

On another occasion, there was an HDR image that had several CLONED spots (due to sensor dust) on it.  I commented that these spots were quite noticeable  and distract from an otherwise good image.   Everyone else seemed oblivious to this fact.  A whole lot of GREAT STUFF and WOW comments...but no mention of the dust spots.

So, have any of you personally given any sort of feedback OTHER  than the usual, run of the mill comments...Y'know like the ones we see on a daily basis? 

On the other side of the coin, have you received any feedback that made you rethink a specific post or correct it in some way?

Interested to see you replies to this.

Thanks
