I'm going to go ahead and say that the original looked better. In the 2nd version, you're over-detailing everything (brick wall is the main culprit) and the pixel work isn't clean.
While the pixel work isn't clean in both versions, it's more apparent in the second version.
Here's what I mean:

I can't whine about the colors too much though, the most glaring problems are the ones I listed. Also, where's the shadows of the house? The overhanging roof bits should cast one, and it looks odd without them.
And also, not to be rude, but you won't make something akin to Ghibli any time soon. The art made by them is amazing and it's not only the colors that make the art, but all the detail and fundamentals. When it comes to detail, there's so much thought put to in, perspectives are amazing, compositions are thought out.
If you want to reach such a level, learn fundamentals, such as perspective, basic structure in perspective, color theory and do studies of actual house and take a note of everything out into them.
Then ask the question of why when creating the design of items and locations. Ghibli art creates believable worlds cause they seem real not only cause of looks, but because the locations show purpose.
Note: do not resize images when posting here. We can resize them ourselves by clicking on them, and it's harder to edit them and show you our critiques.
If there's any more questions, feel free to ask, and I hope I wasn't too harsh.
