If you feel like comparing...
I made a ribbon brush (I think once you know that you can see how it works) and it looks like you did a texture fill on a path? That's my guess since you said Illustrator was involved, and it looks like that's how it could have been done. So I just had to do one pass for each wall. It was extremely efficient and I will be doing it again. Your maze is cleaner, but, it is also the main attraction of this art. Mine was made for a challenge earlier in the year, it wasn't a prize winner but it has got me commissions already, so that's a net win in my books.
I can definitely see we chose different methods of constructing it, and our mazes have different purposes... mine is just a fun little game for the owner of the estate, not a challenge. You're not supposed to get lost. Maybe sometimes someone gets driven over the edge. Yours is like an enormous encounter. For some reason it has a life all of its own. Mine are just hedges, grown by a mean lady who likes to garden, and likes to make fun little mazes.
Illustrator is frustrating. I agree with that. I switched to Affinity Designer. It's less complex and easier to quickly do simple vector tasks, I found.
