fun fact : i do this while babysitting my lil brother, while i draw (without the backround),i see him looking at me drawing.
i said "adik nak lukis ke??" (do you want to draw bro??) and he said "nak!!" (sure!!)  then i said "ok,adik  lukis lah backround ni ok??"
(ok,you draw the backround ok??) he nod then i give him my phone then he start to draw the backround.

honestly he did a good job with the backround!!
