It's certainly a very beautiful map, and I know well how difficult it is to find a suitable real-world base map from which to draw this region, so I think you've done a splendid job with it!

As Sue said, the seas look a little "double-exposed" currently though.

How historically-accurate were you intending to be with it?

I ask, as ancient Mesopotamia is a particular place of interest for me, especially around the 3rd-2nd millennia BCE, along with the Black Sea and places adjacent around the 2nd-early 1st millennia BCE, and east to what is now Afghanistan, Pakistan and western India. They're places I've mapped and studied in some detail previously, and there are points I could make which might be of use, though only if you were wanting it to be more historical.

The river lines are very complex, particularly if you're going for that historical route, and a specific time-frame. The Tigris has pretty much held its course over the millennia, largely thanks to a stonier bed, but the Euphrates has drifted hither and yon across the silts of southern Mesopotamia especially, encouraged by deliberately-dug irrigation canals in places, beginning around the later 4th millennium BCE, for instance.

I know when I started out trying to map parts of this region, something that surprised me was how poorly different published atlas maps compared with one another as regards the modern watercourses, especially for anything other than the major river channels, even in the specialist (i.e. archaeological-historical) literature.

Looking a lot better now!

Yes, I think the walls would work very nicely for ruins too.

If the stepped outer surface was full regulated, it would also work for buildings such as ancient Mesopotamian temples, which had deliberately constructed outside walls that had this kind of "vertical recesses" patterning all round them. I've had to draw these before, both by hand and on computer, and it can be pretty tedious for a larger building plan!

There is an old text-file of the fonts available via a standard Win 10 installation plus those fonts that come with CC3+ and its numerous add-ons and in the Annuals, which is intended for use by Atlas map creators, although it hasn't been updated for some time (and I did run into a problem because of a duplicate font name for the "Mayan" font that came in the 2019 Annual, which I already had installed; so the list won't be infallible under such circumstances for others). The text file is available via this post from March 2018.

I have to admit, I now tend to list whatever fonts I've used in my Atlas maps as part of the Submission document for Remy, which makes it easier to spot if there could be a problem (I hope!). Plus it also serves as a reminder to me to check that text file to see what fonts are preferable to use.

You might want to add a box and maybe a background to the map key here, and move or delete that "50" fathom depth label currently in the key. It looks a little odd to have the green low tide line marker set between the 75 and 50 fathom contours presently, for instance. Might be worth adding a land indicator to the key as well? And perhaps a compass pointer.

I seem to have missed this earlier, and it's been a bit of a battle to get to it tonight - Forum kept redirecting me for about 15-20 seconds, but it seems to have stabilised for the moment. I hope...

Interesting looking map, certainly.

The trees seem a bit overwhelming in places, contrasted with the settlement sizes. I'm not sure if it's as much the transparency issue though with this style; placement is everything to avoid overlaps, and this looks a little messy in places to my eye. Struggling to follow the river lines in places, for instance.

The settlement and ship symbols seem to have ended up on different Sheets, as some are transparent, others not, which also looks odd, as I'm assuming the lack of a key means these variants don't have some particular meaning.

The navigation lines out of Lake Quelimar into the sea also look a bit confusing, unless there's some concealed connection between the two the lines are meant to represent?

Vederit's too close to the northern map border, I think.

Does the darker shading on some of the more southerly mountains have an especial significance?
