I'd like to add one more point about the lighting. Your render settings make a HUGE difference to the look of the scene.
I don't have Colm's package. But for final renders, I know enough to do things like making sure raytracing is enabled, adjusting pixel samples, and shading rate and all of that. I usually render with a shading rate of 0.10 and pixel samples of at least 6-10 for a final Firefly render... but yes, render settings can make a massive difference in the appearance of the lighting on a scene.
I'm starting to thing there is something buggy in the SR3 release when it comes to morphs. I've been working on a set of scripts to Randomize morphs and then remove unused morphs, and after the update they seem different. I can't really explain it, but it does seem like when I add an remove morphs different things are happening than did before the most recent update. I know you just got P11 so I'm guessing you are only on the most recent update.
Hmm. Yes, I did just get P11, but I was having some trouble with doing the update; it just wasn't downloading yet. My connection can be buggy at times; it will drop and come back up randomly sometimes. So I'm actually not running the SR3 yet... maybe that's what's causing the PMD/morphs issue in the first place?
Should I wait on updating for the next SR to come out?
