At first glance I thought; "Thats nice." and started scrolling, then hit the brakes, rewound, and stared at it for half a second, thinking "What did I miss?". It was the beautifully subtle refection. (slightly lower, middle-ish, left side.) So now I must change my quote to "That's actually really nice!"

Just a real quick thought; had a similar situation once helping a pal. If you have the means, most important being something above the ceiling drywall to nail to, you might consider a "faux beam" to hide the ...joint, or gap. Although there are several ways, a cost and weight- considerate method is to simply run a 2x (your choice of width), down the length of your ridge, (make sure its straight), then "box" it in using 1x6 or whatever. Ideally, the base at the ceiling would 'match' your span. ex; 15' long room would look right w/ a 5" w x8 or 9" high "beam", while a 25' room would want a more substantial "hollow box". You seem bright enough so I'll leave you to imagine how that addition could accent ... Plywood is another alternative to box it in, giving you the options of maple, oak, walnut, etc, which of course is pricey, while cheaper ply could be painted ceiling color or any accent/trim color you may have going on. I hope whatever you do, you do safely!

I just wanted to throw this out there, as an ex wrestler. (HS, went to state once, basically sucked at it) w/o caul..... it.s mostly the result of having one's head "ground" into the mat by one's opponent over time, and is basically blood gets between the cartilage and the skin.. kinda like a hematoma if I'm not mistaken, which I often am...
