Although (of course) I still have just a little bit of lighting critiques. I have my brightness set to moody, but it doesn't look that way at all. It's just too bright. Take a look at this dark oak forest with Hafen on its own compared to Hafen with Pixel Reality Luminance (Full). I think the broader dynamic range is more appealing simply because the contrast keeps things from looking flat. This is just one of those things that steps up your pack from having not only great spritework, but a good ambient feel to it as well. Besides daylight, I think the artificial lighting could be touched up. Remember that light doesn't change color based on distance, only in the amount of light. What I mean by this is that torches don't give off white-ish light that changes to orange, but its orange throughout and just gets darker as it continues. Make it any shade you'd like, just remember that the light itself won't change color. Having consistent color will make it blend nicely together when you place light sources near each other. Note how the torch is an orange flame giving off lighting that is a different color in your system, but not in Luminance.
Thanks for the feedback - I'm working on changing the lightmap now. Again a bit of a delayed reply (I just didn't want to relearn how to work the lightmap texture, since it was so long since I originally did it lol), so apologies for that. I'll update you on the progress. Unfortunately, as I'm sure you know, OptiFine isn't released yet for 1.15, so I have to work in 1.14. I can't wait until they update.
