Fun solve! Loved the themers. A few very minor notes: 47D and 42A assume a Northern Hemisphere perspective; 53D feels a bit forced (but I can’t suggest anything better); and 65D might be better as “professional” or “commercial” rather than “economics”.
I didn't even think of that! You can tell where my bias lies, haha, I'll see how to fix that. Good note for 65D also, I appreciate that. 53D, I see what you're saying and I might just keep it because I cant think of anything else too. Thank you for the look-over!
