ahahaha. not necessarily his tastes, but some of his sketches are pretty surreal nonsense, so it's all very 'whatever makes you happy' they group's been around for roughly the last four years, probably do a lot of their scheduling/planning via a group text situation, and often times they pick public spaces like parks to meet unless the weather's foul and they have to take it indoors (sketch sesh in MoMA, anyone?).
adriaan himself is pretty friendly and laid back. jokes a lot, keeps more serious stuff to himself. doesn't generally 'do' stress as a concept.
