BETA 4:
Not quite map feedback, but it is a graphics comment. The Italian MC.200 and Ba.65 and G.55: why the severe shading on the trailing edges of the wings and tail? I noticed that someone had fixed the color imbalance/mismatch of the SdKfz 7, so I figured I'd throw in a comment about them. The graphical style of the other aircraft is just about perfect, but these two stand out a bit as inferior visually.
You missed a trick with the Italian aircraft by not putting the big white cross on the tail rudder. It's one of the most recognizable things about those planes.
Map feedback:
India. Mountains at (24,20) and (20,11) and (18,13) have tiling problems you'll see right away when you look. The jungle tile IMHO, looks too thinly populated by trees; jungle ought to be thick and impenetrable, right? And not just by palm trees...
Caucasus. Mountains tiling problems in several places. I'm sure you guys can find them. There's only one place to look....

BTW, what's up with the flat spots in the middle? They seem deliberate, but look odd. SIX airfields at the bottom of the map seems a little excessive.
East Africa: Kharloum, Asmara, Moyole, and to some extent Addis Abeba (most common spelling "Ababa", but I could go either way) - seems odd that they don't visually connect with the roads in the adjacent hexes, even though the game treats it as if they did connect.
El Alamein: Several towns don't visually connect to the main coast road. I've noticed this now in several maps, but I'm beginning to wonder myself if it would actually look better, so I defer to your judgment...
Kasserine Pass: A few moutain tiling issues.
Malta: DFS 230 - doesn't really need any sound and the sound it does have isn't appropriate for a glider. Mountain (26,24) has a tiling problem.
Mareth Line: Mountain tiling problems in (24,38) and (26,42). Sometimes when scrolling the tops of mountains get cut off - it only happens when I scroll up and down; when I scroll left and right the mountain tops don't get cut off.
On Road to India: Title needs a "the" somewhere; either "The Road to India" or "On the Road to India". The Euphrates forgot to have a delta at (6,6). Between Basra and Chabahar IRL there are just masses of hills and mountains, but I really don't know how you could possibly model this in the map. In any case it seems there aren't enough. Why extend the map so far south? Nothing farther south than row 25 really matters anyway.
Palesine: Initial popup would be better "Arab volunteers have secured the [three] pumping stations northeast of Haifa..." Mountain hex tiling problems near (30,4). Nitpicky, but it bugs me that the Arab volunteers Rolls at (36,4) has a British roundel.
Ras el Mdauuar: Trenches cause minimap hexes to appear green - not sure that is intended.
Suez Canal: Canal tiles are very nice - better than what was there before. They don't perfectly match at the hex borders, though. Very slight, but I can see it. Anything on the map north of row 13 is useless; you could cut it off there unless you liked it for aesthetic reasons. Unlike the East Africa map, the "useless" section actually adds a little to the look and feel of the map.
Random comments:
-Perhaps instead of grouping several airfields close to each other you could allow aircraft to repair on adjacent hexes instead of making maps look silly.
-I think the sand dune tiles could use a little bit more contrast overall. They don't quite stand out enough.
-Guns as large as the 144mm Long Tom should be immobile without a towing vehicle.
-Overall the map beautification is very nice!
Thanks for all the hard work!
