Mickaël Mehala—aka Black Childish—is an illustrator from the French Caribbean island Martinique. After being introduced to drawing by his childhood best friend, he was mentored by an older artist in the area, and when it came time to leave school, he went on to study graphic design in Paris. Now living and working in Amsterdam, WeTransfer asked him to create their new spot illustrations (seen by users as they send and receive files) and we spoke to him about how he went about doing so.
