"Your face pollutes the view here."
Translation:Wajah kamu mencemari pemandangan di sini.
WAJAH is the part of the human body where the eyeballs are embedded and its accessories include a hangout place for the nose, complete with mouth, complete with bad breath.
MUKA, if the human body also refers to the face (because face is in front), MUKA can also mean FRONT if it is on an object or place, for example muka rumah (the front of a house) or halaman muka (front page).
So, the WAJAH must be FACE, but MUKA is not necessarily FACE.
