Here are grades, to emphasize, just for the turn. One big picture thing: Diplomatically, we could be looking at a big 2v2 fight with some combination of France/Germany/Italy/Turkey fighting the other two, or a 3v1 where everyone is jumping on Italy or Germany. In such a case, Russia would be in a really good position to swing the balance of the contest. But we aren't. That's why diplomacy matters! The best tactics in the world can't save you if all your neighbors are attacking you.
ENGLAND: C
Not a lot of options. Still alive!
FRANCE: C-
I do not like what France is doing here. It's very unlikely that anything bad will happen if France is aggressive with Germany. Should Italy take that chance to attack Iberia, Turkey is strong and even if friendly with Italy now, Turkey is about to run out of room to grow. It's not that France is doing anything wrong, if we assume France's goal is to get out alive. But this makes it look like we're going to be cruising to a big boring four-way draw, instead of France making a serious solo effort. There's a chance this is setting up a stab or something, but I don't think it was planned very well if so.
A good general Diplomacy rule: If your immediate neighbors are on the mat, don't let them get up if you can avoid it. France and Russia had Germany in a squeeze, botched it, and now Russia is going to be eliminated while France has too strong a neighbor to go for a solo.
GERMANY: A-
The flip side of my comments for France. Germany keeps France friendly, keeps Italy friendly, has a collapsing Russia to eat. I suppose it's possible there's a crazy French stab coming, but it's not likely to work with Germany getting a build and Russia losing at least two centers.
TURKEY: C
You set up a safer border with Italy, so, cool. I don't like that Italy has the southern fleet advantage, but not a lot to do about that right now. Unlike eturnage, I'm not sure this isn't a planned switch of Greece and Rumania, but Italy getting a build probably isn't good for you, but if you do indeed get Moscow and have a friendly Germany/France, you're OK.
ITALY: C
What eturnage said about Vienna! Austria with a forced disband would guarantee your getting two builds. I can only assume that a. Germany insisted, and/or b. it's some (real or imagined) sop to Austria. The way things worked out, you cannot guarantee taking Vienna and holding Budapest.
On the other hand! You've got options with what to do vs. Turkey, and that's a much more important question than if you get Austria out this year or next year. This turn is an OK turn if you use it correctly.
AUSTRIA: D+
Those weren't great moves, but there aren't any great moves available to Austria. You should have know Italy would be trying for Budapest, and it was a reasonable guess Galicia wouldn't be cut, but things aren't really easy for you.
RUSSIA: D-
I think the most striking failure in this game is Russia's inability to maintain a good relationship with France, which likely costs Russia the game. Tactics on the turn were fine, but selling France on a war with Germany should be more successful than this. Russia's only hope now is to find and exploit divisions among the four strongest powers, who are all right now Russian enemies.
