Not a boring KL
Just change your mind about nothing to capture in Kuala Lumpur :D
Malls
Yes, you are not mistaken, there are plenty of malls located around Kuala Lumpur, each has an individual beauty.
Playgrounds
Most of the playgrounds are located inside the apartment, please be careful when you want to have some shots with them.
Religious places
Malaysia has a religious diversity and of course, we can find many impressive architectures there, just in KL
Train stations
The biggest difference between KL and HoChiMinh city is the train stations. In my hometown, there is only one and it's still under construction. There are some stations which have a nice view and you can feel the movement of the city when capturing them.
Bars
Oh, I mean we can go there for some chill and enjoy the sunset — i would suggest 2 best: Trader Hotel and Vertigo (Banyan Tree Hotel)
