As I see from the picture, I can point out three mistakes:
1: The basement height is too High for the building or maybe the floor height is less.
2: The lintel is combined together with the beams (maybe that's due to increased plinth height) which I think is not good, Atleast they would have merged the lintels with the beams' top.
3: The reinforcement bars above the slab are unprotected and rust is quite visible on it.
Well that's my opinion maybe I'm right or wrong.
