Here's my two cents:
As usual, if I didn't like something, it is very likely that someone else did like it. Furthermore, this is not to degrade the author's creativity or the amount of work put into it.
Now...
Fooled and Fooled Again
This encounter was a little short for my tastes, a little underdevolped. I didn't see much of the encounter location.
Furthermore, with "Folled and fooled again" I had thought a more intricate plot would come, like the brother telling the PCs they have been duped into buying a false map, offering to buy it. After much to and fro, the party is totally confused and has lost lots of money through their own stupidity.
Somehow, this registered with me as lacking.
Blood of Angels
I actually didn't mind the fourth page here; at least the page margins and font size was accurate, and only two lines swept over, so I regarded this as still in the boundaries of the rules.
However, somehow I didn't see the connection between the interesting NPc and the town.
Furthermore, the concept of an evil deity giving good spells and allowing turning was not unconventional, but something to carefully consider. Together with the divine sorcerer, this was a rather "oddball" encounter.
An Imp in Set's Clothing Gets Help from Scaly Friends
An interesting location indeed. i could already see it's uses in campaigns as I was reading it.
The NPc was a nice touch, too - and it had lizardfolk!

I almost voted for this encounter, but for the imp having a half-orc form to change into, and then using this with change self. I wasn't quite sure if that's viable.
And the best part was that the encounter fit three pages, plus had a map!
Excellent work!
Shrine to the Flying God
This one was quite interesting, too, but I had several problems with it.
Technically, the location began halfway through on the first page, and the stat block was written in "Arial 7pt" instead of 12pt... So clearly, this entry didn't follow all the rules.
Storywise, I didn't fully understand the "feather fall" ability, as I thought the featherfall lasted for 2 hrs., but then the sorcerer traveled ~15hrs with it.
Lastly, the sorcerer didn't notice that he has lived far longer than to be expected, and has accomplished more than he should have. This is mentioned in the encounter, yet an explanation is not provided. That was a definite flaw.
Quiet, Please!
This encounter filled 5 pages, so the rules were clearly not followed.
I liked the style of the writing, but a lot of space could have been saved if it had actually been a more conservative format.
I wasn't very sure whether the vampire was reknown in the vicinity, too.
Furthermore, the connection between the vampire and the library was rather vague, if not nonexistant.
Still, a nice idea, and I might use some of it.
The Last Kiss
This encounter did follow the rules (see below), it tied the NPC and the location, and it had an interesting location complete with map (well, it's an Inn, but still) and an somewhat unusual NPC (although sukkubi don't seem to be as unusual as you might think).The only problem I see with the encounter is to get all PCs into the cages. After the first one (or the 2nd at the latest) has been lured into some unusual erotic pleasure and brought into the cage, most players would act suspicious nonetheless, at least when they see their friends being already in a cage.
Still, that's a minor peeve, as the Pcs should be charmed by then.
This is the encounter I voted for, as it connected NPc and location, detailed both, and followed the rules - even though the margins were stretched to the sides to fit it all on three pages
The Five Keys
Font size 10. Making it 12 showed 4 full pages without page break, and jumbled the charts.
I liked the premise, though I found the idea of a one-way portal into a hideout a little strange. I might still use it, to get the PCs on track with a forgotten adventuring group, but ...
I think a nice touch would have been if the elf had outlived his friends, but the grief made him forget this and he thinks of them as "far away", though they are long gone.
Still, didn't follow all the rules.
Persephone's Glade
I was kind of confused by the description as the location was meant to include the dryad and the pixie, so when the NPC was introduced it felt as if it was a different encounter altogether.
Furthermore, I wondered why this glade was so magical, why there was never rain yet plants could grow, etc.
This could have been explained with one, two sentences.
Otherwise, this was a nice encounter, and followed 8as far as I know) all the rules - even normal page margins!
Forest Dragoness
The encounter easily fit on three pages, as all descriptions were held rather short.
The location was very tied to the NPC, and you would have to tweak what little there is known of it to remove all traces of the Half-Dragon.
I also didn't see right away that the Pcs were meant to be ambushed near the villge, instead of just somewhere within the forest, but this could be me.
If this would have been a little longer, and the village also detailed without mentioning the Half-Dragon, this could have been great. As it is, it is nice, but my votes go to Last Kiss, nonetheless.
