well done for improving your work, definitely looks a lot better. There's only really 2 things i can suggest that might help your piece a bit one.
Firstly, i think make your black outlines slightly more transparent, so they're not as visible. If you look at the photo, you can see the black lines are there but they don't stand out quite as much.
Secondly, and this is a tip i used all the time for lots of different things (even in vfx), try squinting at your painting. Do you notice the brightest part and middle part of your building merge together, almost into 1 colour? Then try squinting at the photo and you should notice that the brightest part is still noticeable and separate from the slightly darker areas. In short, make your highlights slightly brighter so it stands a bit more. I think this will really help your piece pop out.
great work though, keep going! The tree's look nice
