Well, here some criticism:
First of all, I do not know if it is proper to make scenarios about the crisis that hasn't yet resolverd. It is just my opinion of course and it is not for me to decide. The main reason is that future events and resolution of crisis are not known. So many concepts of scenario have to be changed later accordingly. Such is victory condition for example.
Again it is only opinion of mine.
Now about the scenario itself.
1.Map.
The map seems to me too big for a scenario about Ukrane. Ukraine occupates only a very small part of map and countries that not really involved in conflict have much more terriotry. Personally I'd like to see the map of Ukraine only or even only separatistic states. The map is just too large to reflect events in key locations. There are only Donetsk and Sloviansk for DPR, but there are battles at Kramatorsk and nearby villages.
In short, too large scale for such a scenario IMHO.
2. Civs
Theres a bug with Moldova. It stated to be unplayable but I still could choose it at the starting screen. The second thing that surprised me: Crimea is independed (and at war with Ukraine!) and Luhansk is not. In fact Crimea is a part of Russia now and there are now any battles near it at all.
Luhansk proclamed independance along with Donetsk, so it should be a separate civ as well. Crimea should be a part of Russia.
And again, too many civs. Finland do not participate in conflict at all. Ukrain, Donetsk, Luhansk and Russia, Belarus, NATO unplayable (I think., even NATO is not necessary). And Russia could be represented only by Crimea and some cities and villages on border with Eastern Ukraine. Western Ukraine is not necessary as well, I think.
3.Gameplay
I started with Donetsk. Well, no industy. There should be at least some buildings, like Police Office, Armory, Civil Defence of something like that. And how can they build mobile SAM's? If I were you, I'd redone all units. For separatists I'd like to see not only armed rebels but civilians with bats, Molotov cocktail, armed civilians, captured APC's (not tanks), RPG's or something like that. For Ukraine: national guard, Right Sector forces, APC's, strike helicopters etc.
After the first turn Ukraine signed military alliances against me with almost every nation including Russia. The last was at least... strange. It's better to remove alliances and packts at all. On the second turn Russia declared war on Crimea. And that was just... absurd. I made some more turns.
Urkaine didn't send a troop on my barricades (they must have some near barrickades). Only landed a special force near Donetsk. But Russia moved some tanks and machinegunners, so I was unable to make turns anymore (defeat was just a matter of time). I think, Russia should be removed, but some border cities. The same about other large countries. Locked alliance with Russia wouldn't be correct. So you should think about reducing enimity and not only towards Donetsk.
Barbarian reberls around Kharkiv also look strange. If they are also separatists, then only Ukraine should attack them.
And the only victory condition is conquest. So Ukraine or DPR must capture Belarus, NATO, RF and others to win?)) I think, VP or even Diplomatic victory will fit much more. Again, as I told earlier, we do not know, how "the victory" will look like. Will separatists be defeated or protect their independance. If the latter occures, will they stop or march to take Kiev? Or everything will be resolved diplomatically. Or full-scale war will break out? (I hope not))
Anyway, in my opinion, conquest is probably the most unsuitable condition of victory.
That's all I wanted to say. I hope it wasn't too rude. Just what I think and I can be wrong. Anyway it is for you to decide to change things or not.
P.S.: Forgive my English. I hope that my point is clear.
