I will tell you how to draw the town of a bird's-eye view easy.


First : Make many kinds of squares.

Change it along with Perth.

and copy two of them.

Extend one of it perpendicularly.


and another one ,　shift downward. and change the color to dark



they become buildings　easy

Also build the pool of a roof by the same method.

plant　greens in some crevices between buildings


Yes, looks good !!


Make shadows

copy and paste


Make details of parts of building , for example pipes ,ball tanks ,fences,and others.


OH
good


Thank you
