I took time to answer, sorry.
Here in Brazil is Carnaval, then you just imagine where I was.
Well here we go:
The perspective of the train was only to make a presentation at the beginning of the game. There needed to be in the proper perspective. I mad it, before play Spirit Tracks. But thanks for the tip. When I finished the wooden train, I will take into account ...
The home of Outset island, is not yet the final version. The colors have not pleased me. The hatch of the straw is also not good. I better I study the roof of Link's house in The Minish Cap game, there is good tileset.
My biggest problem is Thorned Fairy Isand, because it hit the hatch and the actual colors of the shell. I would really like someone could help me with this.
Regarding the black outline, I gave a change. Here is a new image of what has changed.
Thanks for the reception.
