Wow! Some nice entries this week!
Mine is not completed yet. But here is a WIP render:
I saw many cutaways of houses on the internet (archviz stuff), and followed the same idea, but I decided to give mine a story. This house has fallen apart as the ground gave way, leaving the rooms cut open.
I still need to find some textures for the wood, add lost of debris as well as insulation spread everywhere, and some backdrop.
Critique please, anyone?
Decent unyxium!
You might want to check out what Depth of Field can do for your image. Also, the background is a lot of blue. Perhaps u want that spiced-up up a bit too. You could combine both tips into a heavily blurred building/windmill/church/… in the background or some kind for a huge time saver.
I didn’t know there was so much glass in there until today 
Nice entry, since u wrote about BPT I had to look it up, glad i did. Lots of use for it! Thx for mentioning.
Work in progress. Still struggling with the tiny little details amidst a flu.
This will be cutaway of a giant space fruit… lol jk.
— WIP — (finished entry is below)
Here is my non-competing entry:
ANY WAY THEY SLICE IT (A PARABLE)
Pure Blender 2.79, Cycles, only procedural textures.
Needless to say, please click / tap for full resolution (or perhaps view image directly and expand to 100% in browser).
Low poly / stylized mainly due to time limits, but I think it seems to suit the subject matter 
Interesting technical note: this was all modeled and rendered in one big scene (a live Cycles render):
Inspired partly by various cinematic “cutting” techniques, such as cross-cutting and cutaways:

I simply loved the squirrel on panel three 
Stellar Engine
Pure entry. Cycles 512 samples, procedural textures only, all works done in Blender. Also trying out fancy title/caption effect once in a while.
Possible continuation of the story on The Ring (WC #745). Since some details got lost in the glare and due to the view angle, here are some more views:
Still not too satisfied with some details actually, but this should do for now.
Fashion
Open entry. Continued fussing over last week’s model, and added a previously created scene.

She’s wearing a cutaway jacket. I probably should have spent more time on the clothing.
1000 samples with despecling.
No time this weekend, too busy playing with my raspberries, I have however just scribbled this post, We need to talk about Discourse
Unstable Ground
Pure, competing.
Cycles + compositor, 256 samples for a ~10 minute render.
This took a while to make.
I will be sharing a time-lapse video of the modelling soon. I will update this later and possibly create its own topic.

Edit:
I wish I was a modeler, I have a cool idea for this one involving a parachute
Slice of Life
I collected some of my entries which had some impact in my Blending life one way or the other. They are organized chronologically, with earlier ones in the bottom and newer ones in the top.
I think this was my first attempt at doing architecture. I did a lot of mistakes (wooden floor looks horrible), and because of the time rooms ended up being way too empty. But I’m happy with it nevertheless.
Cake
I am still quite new here, and am not quite sure whether to call this pure or open. To be on the safe side let’s call it OPEN.
"Recycled Rocket"
Non-competing. I rarely use old models, but I’ve been too busy with other projects, the rocket is from an old WEC.
Incredible entries all! One of the best showings ever in my book.
