Came in to say how JP forums works over there is they have one 'official' feedback thread, most people will post high-effort feedbacks with multiple pictures with fair comparisons (same light/angle), pointed out the problems on the pictures (some even with drawings), stating their opinions both good and bad, suggesting how to change or improve, in a clear and constructive way, very politely, and leave.
No quotes. No arguments. No drama. These posts are meant for the devs anyway. No reason to fight.

For example I find this post gives a simple solution to their m viera lips by giving slight gradation retouch on lower lip that could work really well in practical.

We can totally give helpful feedbacks and comments without hurting any parties. Everyone here are human after all.
