You've removed most of the interest by removing the contrast in the wall tiles, though the sidewalk and cobblestone look better with the new colors.
Sharm's edit made your dreary look much more interesting to the observer (who are you creating this for -- you, or an audience?) and Probo did your construction some justice (an extra 16x16 tile or two I don't think will hurt to make your buildings visually appealing, unless it's a limitation on the game engine, though if that's the case, you might want to try a more modern one). As I don't like to be an ass about this kind of stuff, I do feel like people are offering you an awesome amount of help and you're just saying "meh, I don't care what YOU think should be changed, I like it because it's mine, so I'm not doing that. But help me some more."
That kinda defeats the point of critique, doesn't it?
If someone brings up something about your art, although it doesn't always need fixing, it does always need addressing in an objective manner. I almost didn't respond to this post because I thought you were being an ass at first by tossing (experienced) people's advice aside and saying "I like *mine* better." without ever trying to incorporate even a little of the advice they were giving you. Even if you do like yours better, you don't have to change your entire art direction -- just try adding a little something new to it. After all, drab colors or not, your windows are still too low and too large, and someone has already tried pointing that out already to you, which you also ignored.
I posted to this topic because you have potential, and I don't like that to go to waste. The most important thing I've learned about art is that the more you think you know about it in terms of style or technique, the less you really do know. That's why you should really try to take in everyone's advice to some extent and try to make it work for you in a way that you are satisfied with. Otherwise, critique is useless to both you, and to the person taking the time to hit that reply button, hoping you'll not ignore their time and energy (the older you get, the less you have of it after all, so the more valuable it becomes to you).
Just food for thought.
