First off, very nice AAR.
I, like Klydon, see trouble in the South. That line of Romanians along the Dnepr....remember, the Dnepr basically disappears after the first Blizzard turn, so they will just be Romanians defending in the open. I.E., Dead Meat. That is problem area #1. If they fall apart, that's pretty far in your rear. Major problems. The line down there is crazy-long, but in the Blizzard, this favors the Russians.
Up North, I would stretch the Finns as far as you can toward the South; they can take care of however much line you can give them. That will free-up about 6 divisions or so in 16th Army; I think you need them in front of the Valdai Hills, where you also look thin.
Maybe you planned these changes before Blizzard, but just saying.
