I appreciate the feedback!
I might have to fix something audio-wise on my PC cause it's much louder on my end, but that complaint is consistent with other feedback I've received about my setup. Edit: I reset some settings and it is much quieter.
I'll also value that art advice highly, I'm a novice on that end and still tend to just feel my way through it. I myself was unsure if just darkening the tunnel would be fine, but I see now that I could've done a bit more to convey my intention.
