Exactly Matt, I believe..

Good learning experience for me. I've heard of Reciprocity Failure, but never could get my head around it.
Is there an exposure problem? It's possible I'm mis-interpreting what you were going for, but your exposure looks right on to me. The question is the foggy portion. If reciprocity failure were the issue you wouldn't have a picture at all, at least not in the dark portions.
Not sure about the fog.
Horace, that's what has me scratching my head. According the folks at FreeStyle I should be considering RF at 8 seconds, but then again, you can read the numbers on the dial. Maybe I screwed the pooch in development.
It's all new to me, as far as long exposures go, if you want to consider 8 sec. long. It was for me.
Your mention of "kind of foggy looking in the middle" and the location of that area suggests to me inadequate fixing, perhaps largely due to ineffective agitation. If there is truly any milky appearance in that area of the negative, I would re-fix with good agitation and re-wash as a first step. I ran into that situation with a foray into 4x5 film in pinhole work a few years back. In my case it was a T-grain film that seemed to need more than the usual time in the fixer.
Yes, that foggy looking area looks like it may be inadequate fixing to me as well. Does it have a white-ish, milky look to it, especially when it was wet? If so, it's a fixing problem, either your fix is spent, contaminated, or you just didn't give it enough time. Another round of fixing should take care of it.
Note that if that area were due to an exposure issue, it would likey be less dense, but but since it looks light in a positive, it has more density.
Other than that, since there is so much shadow area, it will be a thin looking negative no matter what The area away from the cloudy part looks ok, given the conditions you've described.
Update: It was the fix. I dipped it back in the fix for 2 minutes, and washed it, and the fog is gone... ;)
Didn't know you could re-fix a neg. Nice to know though.
You can not over agitate fix. I always use excessive agitation. Film is by strict pattern, time, & temp.
Flare due a reflection off an item that wasn't noticed?
iwouldextendmeasured 8s to 16 actual seconds of exposure due to reciprocity or go from f16 to f11and avoid much of the reciprocity issue. also counting time is highly inaccurate. get a stop watch or a special timer for long exposures.
I find when counting one-ansel-adams, two-ansel adams, etc, that the accuracy of my timing is well within acceptable limits...actually I tend to count slow, if anything, so that helps to take care of some of the RFailure.
Of course what one considers acceptable limits will vary a bit.
