Tried on the straight face first... Used a permanent marker with a fine tip to draw the at right side first to test... somehow it makes the eye look a bit bigger visually...
After drawing on both sides... looks ok...
Comparison with the smiling face... I drew the eyebrow on the smiling face too (did not take the picture), but it still does not look that good...
Fit the straight face on the head... Looks better... but think I still prefer the shouting face...
And finally managed to fit Jinbao Megatron onto the display stand... turns out the tip of the peg (of display stand) has too sharp edges and caused the difficulties I faced in the video...
