No comment on the phytogeography map I gave a link to? (Since that sets limits to what kind of culture is possible in a region, it's directly relevant to the ancient history you're reading at present). At 219K it isn't that big, and it's fairly uncluttered.

If you won't tell us what specifically is wrong with suggestions offered, how can we suggest anything better?

(I once played for some morris dancers who used an incredibly limited repertoire of tunes. Playing those every week on the same instrument was dull as fuck, considering I wasn't being paid to do it. But most of the alternatives I came up with to add variety were rejected with NO, THAT'S WRONG - with no hint of *how* they might be wrong. I gave up in despair. This is feeling like a rather similar experience).
