How long does it take to draw a diagram?

How much time does it take to draw one building?

I work with Photoshop (pencil & brush) and draw with 1:1 pixels.
It takes about 30 minutes to 1 hour per building.
(For tall or complex buildings, it takes longer.)
The pixel pencil brush draws the whole thing, and then the multiplayer and overlay layer have light and window effects.

I refer to Street View when I draw a building. (For example, the U.S. building is Google Street View, the Korean building is Naver Street View, and the Chinese building is Baidu Street View.)

If Street View isn't updated, I draw it by looking at the actual image or concept picture.

I wonder how you work
