So I've been through the entire thread now, and all I have to say is 'Wow'. I love the style, very unique. It's incredibly colourful, and would do incredibly well for a game such as the wind waker or similar. it feels incredibly happy, and your spriting skills are quite impressive.
I like that you've taken inspiration from other games (Minish cap for the house interioirs, lttp for the trees) whilst holding your own style.
Looking at your most recent tilesheet, my main criticism would be with the logs that link walks through. The shading on the horizonal log makes it appear as though you are looking at it from directly above. Whereas the trees and houses imply a slight angle. I'd work on the shading to perfect them.
