Ok, my not-so-expert opinions:
Boss/FE task
Whispers: A nice idea, and good job on all the achievements. But it just seems too complicated and difficult to start off with. It would be better as a long standing game, not an event.
Ferns: Cool idea, but too darn complicated. Seriously, I got bored reading through the thing, and that's bad.
DDD: One word: Neat. Good event, though it's bit too similar to PvP
Cuckoos: Fun little event.
Artist/OT task
Whispers: One word: Bleh. Could've been a lot better.
Ferns: Lol. Totally perfect way to do this task.
Cuckoos: While having a new game is really nice, the implementation of the video could've been better.
Card Designer task
Cuckoos: Lol no. Really unimaginative in my honest opinion.
DDD: Nice idea. But the card text and the description could've done with a bit more work.
Ferns: Awesomesauce. Fits in thematically but utilizes an off-element mechanic perfectly.
Whispers: Another awesome card. 'nuff said.
Deckbuilder task
Ferns: Thematics are spot-on, but using only one CIA card wasn't really what I expected. Mainly cause it's just a normal deck modded with Foliage.
Cuckoos: Thematic perfection once again, but one CIA card really doesn't make it new enough.
DDD: Lovely spin on the basic Kitty deck. It's much more effective, but meh.
Whispers: Really effective deck you got there.
Writer Task
Ferns: Good job there, totally rocked the erotic theme. But I was kinda expecting the ending, would've worked with a better joke
Whispers: The whole story's just meh. I'm too bored to do all the clicking on that site ofyours :/
Cuckoos: "that piece was beautiful. Amazing work on pacing, really awesome references and just WOW on, well, everything. Ima gonna +rep you now."
