That's actually very helpful, and I never realised that you could do that. Thank you @jslayton

No more squinting at entity numbers for me!

Nice @JimP
Turning the effects on makes a big difference.

You could perhaps move the trap doors and pits onto the "symbol flat" layer to remove the shadows?

You too Hans!

I've just started reading the intro to your mapping guide from the blog - thanks for writing it. 
At the very least I expect that I'll be using some blobs in my battlemaps.

For the effects to stack, you sometimes need to add an extra sheet (with the same effects).

This is because CC3 treats overlapping areas on a single sheet as one "item" when generating the sheet effects. So if your hills and mountains are on the same terrain sheet, they'll get the effects run on them once. So perhaps you need a Terrain Hills sheet adding above the Terrain Mountains sheet on the list (so it's drawn first).

As Sue says though, it's better to include a screenshot, so we can see what effect you don't like.

I really like this map @AleD, seems that I forgot to comment last time. 

Did you add the text outside of CC3, or just tweak the contrast?

Thank you both.

@Raiko Super well done!

The new cave looks much better to me, I love it.

Yes, the original was always likely to be a placeholder, I just wasn't sure how I was going to do the walls. I'm glad that they turned out nicely, there are quite a few cave areas in the adventure and I think it's a lot more of a challenge to get a nice look to caves than dungeons or buildings.

Pothole Road made me laugh, they could call all the roads that around here!

Welcome to the forums @MoonBrew.

Any of those PNG assets are usable in CC3 / DD3, I use forgotten-adventures assets in my maps, together with assets from Tom Cartos' Patreon.

They don't come packaged up for CC3 though, but it's only a few minutes (seconds really) work to import a pack of map assets into CC3 as a symbol catalogue once you know what you are doing. The main problem I've had with Tom's assets are the long filenames, which cause a few problems until you've got used to working around them (easily fixed). Forgotten-Adventures assets import with no problems.

You just need to import the assets packs yourself, rather than the prebuilt Dungeondraft packs. From what I've seen on the sites of those asset makers, they'd happily distribute their assets as CC3 symbol catalogues, but a member of their communities would need to set them up.

There's a great set of assets and bitmaps from Mike Schley ready made for CC3 available in Symbol Set 4 - though it has nowhere near as many assets as say Forgotten Adventures.

Certainly though, you can map in whatever style you like in CC3.

I've not actually done any mapping since my Tomb of the Witch King map for the competition back in April.
This is due to various real-life stuff, as well as Elite: Dangerous.

However I've just bought the D&D 5th Edition Player's Handbook, and downloaded the freebie DM book for now, and I plan to run the Age of Worms campaign for my daughter.

The Age of Worms was published in the old paper version of Dungeon magazine, back when Paizo produced magazines for Wizards of the Coast. Age of Worms was the second "adventure path" campaign written by Paizo, about two years before the birth of Pathfinder.

The first part of the Age of Worms campaign mostly takes part in an awesome low-level dungeon called The Whispering Cairn, located near to the town of Diamond Lake in the World of Greyhawk setting.

Here is the original map of the entrance area taken from the free web supplement for Dungeon Magazine Issue 124. This image is copyright of Wizards of the Coast - however it is freely available in a pdf from Paizo's website.

That's a fantastic, beautiful map, well done.

One thing that I noticed, that you might fancy tweaking is that some of the roads are casting wall shadows, so they appear to be elevated - whereas the city walls aren't, so they appear to be flatter than those roads.
