Wow I really like the church; it has a history feel to it. I have been thinking about starting up a pixel church myself of the old brick churches they look like old castles!! I'm not sure if it is finished or not but it could use some shadowing on the church itself to make edges really stand out and give more contrast to it.
not bad, but 225 colors are deffo to much, checking your palette, which is full of nearly equal yellows and greens i assume you haven't yet explored the palette-chapter in pixelart.. an appropriate number of colors would be, say, 32
i'd also recommend darkening the side of the church which's inside the shadow (without icreasing the color-count of course =)
The colors are (as already said) a tad bright, but still very nice! I particularly like the detail on the stone walls surrounding it all
