A practice to draw one of my big weakness, it's buildings

Paint it with so much doubt in my mind, how must the color be? How to create effects on the wall? How to make it more manga/anime-ish?

The final result is very different comparing to what I wanted it to be, it becomes so realistic
I use some photos for reference anyway...... I think it affects me TOO much
The perspectives is still off, I lost my patience when it came to ruler, straight lines and, measuring it’s not a good thing
painting is about expression, and pesrpective is absolute.... two different things

The other weakness is, the back light….
My habit of painting so much detail on the face is back stabbing me when it came to paint back light
Besides the colors are different

I still have to do so much more practices

kill me for those cables, I draw them because the picture was too plain
