Really like this hack. I'm looking for a way to play CtL but without the rules heavy Storytelling system, and this fits. I feel that City of Mist is a perfect system for the duality of Changrlings, trying to balance the mundane and magical side of their lives.
For the setting, it appears to be easy to adapt the changes to be more in line with CtL (I miss some of the Seemings and Kiths from there) and bring back some of its darker tones. But I like some of the changes, like the world be more magic in the mundane side as well.
Also, are you Brazilian? If not, nice work on adapting Rio de Janeiro to the setting. If you are, is there a Portuguese version of this game?
Again, nice work, and looking forward to the updates!
