If you're finding the mapping a drag, and not really enjoying it, it may be worth considering a broader-brush approach to the city overall - such as the Watabou style, that shows general areas only, with just a few important places highlighted, roads and general layout. Then if you feel so inclined, you could add detailed areas for selected spots as separate maps - that way, you don't need to worry about how the map looks zoomed out, and can pick area sizes to better suit the time and energy you have available for detailed mapping.

As Sue said, what you've shown here looks good in detail, but if it's not inspiring you, it may be worth a rethink, if only for next time.

Well, I'm at the stage now where I'll probably just get to be usefully familiar with about 25% of CC3+, and then they'll move us all to CC4 😎!

Looks nice!

Maybe a bit more contrast for the river and road lines in places, so they pop better on the greyscale?

And just a quick note of congratulations to Royal Scribe on contributing this month's Cartographer's Annual issue! A fine example showcasing what CC3+ can do. Well done!

Fragmented walls are - as shown - for surface ruins, although you could use them for a partially collapsed underground area too. The symbols in this OSR style can be as versatile as you make them, mostly because they're not always obvious as to what they're meant to be (name-labels notwithstanding!).
