You'er right, looking at it again, she has a glow to her, but it's not quite the same, I think. Maybe it's the colors, but in motion it almost looks like they're shifting.
Speaking of the ending, I really prefer the bloomed out look of the original more here. The way the lighting washes over Mono as she wakes up just gives the scene a completely different feel, for me anyway
Or when Agro comes back, overexposed lighting as the music rises up makes it all seem much more dramatic and impactful. Or maybe it's just nostalgia!
In general I wish BP had at least retained the the way the lighting looked in the Shrine of Worship.
But for me where BP really dropped the ball was the credits sequence, which the original's are some of my favorite ever. They replaced the memorable, colorful, even bloomer visuals than usual with drab, monochromatic tones.
Every colossus gets its own color scheme. Then in the remake you just get a collection of forgettable greys.
Anyway that's my two cents on that.
