Would it work better if the curled scrolls faced towards the viewer, instead of away? That's basically the way someone would read/view a scroll in many cases, so it may be that's what's making them look a little "off" just now.

Getting lighting to look right and yet still leave the map usable is a tricky balance from my limited experience. In an environment such as you've drawn so far, the lighting would be likely good and fairly uniform flat, or largely none at all, for each particular area, so it may be worth asking how many lighting effects you really need before embarking on setting it all up.

I think this may be what you need to see/read.

Sue's advice is excellent for adding your own clouds.

If you might be interested in using symbols instead - or as well as - you may like to see the Alyssa Faden style pack, which was part of the Cartographer's Annual in 2014, as that comes with a number of cloud symbols designed specifically for use on overland maps.

If you find you've placed a door the wrong way after it's cut the wall, you can simply move the door symbol so it's the way you need it.

You can also turn off the Smart Tracking by clicking the check box in the Symbol Parameters pane (right click when you have the symbol on your cursor). This will stop the door aligning to the wall whichever way it wants (which may cause problems if you're trying to get the door properly aligned with the wall, however). It will still cut the wall as normal, while you have control over how the door is placed.

If you click the Disable Smart Symbols box, that will stop the door from cutting the wall at all.

This applies to all the Smart Tracking wall-cutting symbols, incidentally not just the doors.
