How and when did you start drawing?

I graduated as a fine artist, around 2009 I believe, from the HKU (Fine Art School in Utrecht), where I focussed on painting. I created abstract, geometrical and precise work. To pay my rent I decided to make drawings to earn more money. The drawings would take less time since my paintings took weeks, mostly months to finish. I never thought I would fall in love with drawing eventually. Drawing enables me to awaken the stories in my head. My love for nature and her diversity in flora and fauna can get a stage. To my drawings, I can add sounds and movement and motivates my imagination endlessly.
