This group of interrelated projects is called “Improvements” because that is what they represent to me.
These worn-out old buildings symbolize anything from a country to a person who are in need of help or repair. The additions of sewing, ink and paint are symbolic of an attempt to improve the situation.
However, they are perhaps emotional, rather than rational, attempts to help. After all, they do not fix or repair, but only improve aesthetically.
More globally, I feel that those who are in power have the means to make change and do not. Meanwhile, those without the ability to make a difference (but who need help the most) can only make uneducated attempts to help.
