Hello there.
I've been working fertively on a novel set in a fantasy world vaguely analogous to ancient Rome and the Silk Road, dealing with a time equivalent to the Crisis of the Third Century, and I'm trying to map it. I have nigh-on zero experience with fantasy mapping, so I thought posting it here might net me some useful advice and criticism.

As you can tell, it's loosely analogous to Europe, but only loosely. You've got the Inland Sea in the middle of everything (well, certainly as the not-Romans would see it) with not-Egypt, the cradle of civilization, on its eastern end, the fertile regions around not-Rome in the northwest and a more mountainous arid region in the southwest. North of all of this is a vague cultural region I'm thus far only calling "the North" (whereas they refer to the not-Roman Empire as the Southmarch, as opposed to the Northmarch which is the area north of their own limits of settlement - as you may be able to tell from the abnormally high level of detail, I've brought the region in wholesale from a previous universe of mine), and east of it, the loosely-governed cultural sphere of not-Russia exists entirely separate from the Empire, which is all just as well because the Empire isn't particularly interested in it anyway.
East of that, which I haven't mapped yet, a series of unstable city-states and tribal confederacies lie along the roadways connecting the Empire with not-China in the east. That's beginning to change though, as the city-state of not-Palmyra/Samarkand, formerly allied to Rome, is rising to hegemony in the area. Again though, I haven't mapped any of this, so I expect more details would come when it shows up on the map.
Now, I've started out drawing this by hand - this is mostly because it's the only way I know how for things I can't trace off existing maps. Somehow it feels sub-par when I do it on the computer. That said, I may go on to turn this into a computer-drawn map as it progresses.
