It is something I always wanted to do, to draw the face of my kids together with their favorite things at that age. My boy 4 years old, he loves dinosaurs, cars and panda. My girl 6 years old, she loves horses, dolphins and gemstones/crystals.
I drew mostly with pencil on a plain A3 paper, then with BIC ballpoint pens. Colourings were done with Copic alcohol based markers.
