Woah. The first one looked like a wallswim until I realised she was standing on the roof. The bottom one, with the grass, is also a bit hard to grasp. But I'm sure they both look great in the actual level.
They all look better when your actually moving around inside the level itself.
And yes, the roof is actually solid too, so you can climb up there for a *censored* later on...
Sorry to be a pessimist, but I'm doubting that this will ever be finished. 
Are you the only one working on this? It just seems so ambitious... Don't give up though! This will be epic if it gets done. Unfortunately, the screens are just ok. They need some more decoration. Sorry to be so depressing.
Your not the first to think that, and sure not the last. As stated, I has gathered a small team to help aid in the music, the occasional tileset, and mainly beta testing. There's no end to my ambition....
There's a small team of us working on it. Tch! Pessimists...
By the way JC... congrats on graduation!
Thank you Utherdoul. It still hasn't really set in that it's over though... lol
oh yeah if you google "nifflas tilesets" it links to this ks level thing.
top 5 results 
but it links to the old forum though..
Alright!, I'm google worthy... err... in a past
life account.
This will probably be the most popular knytt stories level if it is released, and delivers everything it promises (large teams help there.) I just really hope it actually makes it to our computers. 
PS: Hey, I just realised, I got post number 100 lol. 
Well no large teams here. I'm doing a majority of the work, creating most of the tilesets, all of level design, etc.
As much as a large team sounds great for the project, I kinda see this level as .... what's the word.... my baby, and I want most of it's growth to be directly from me, not some form of day care. If that makes any since.
