I quite like it myself! Because you worked with a more compact space you definitely had to be more creative when deciding where to put stuff, and it's cool as an observer to be able to see that (perhaps I like it personally because whenever I build it's generally compact itself).
As for the roof, err the shingles or whatever, the original physically sticks out on top of the columns, and I feel like your version could have something like that because to me it kind of looks like the columns were just stuck onto a building, if that makes sense, because the columns don't really seem like they would actually be supporting anything. It may be more of my personal opinion though.
Yeah, I'm worried about the top. As I was making it I grew less and less sure about it.
I also think I tried to make that slight overhang, you can slightly see it in the picture, but I don't think I let it protrude enough.
I actually technically started building this about 2 years ago, but I decided to remake it because of factors such as building experience and new bricks (these 0.25, 0.5, and 0.75 bricks are great!).
EDIT: Ok, there was an attempt to change the top of the building and I'm a bit more satisified with it now.
