Life before digital art.
Its just the ball pen and some highlighters. Good old days.
It would also mean, it cant be erased.
So you will see plenty of mistakes in my drawing. I discipline myself to reduce bad lines and accurate strokes with the pen. Otherwise I start again.
But the personal challenge is very fun. Its tough but its fun.
These are all taken from my sketch book. I carry them around like how people carry their handphones around.
