We’re mixing up the fan art today, and not only posting something from Deviant Art (as opposed to Twitter), but also King’s Quest IV related!
Artist RanmaCMH provides a beautiful drawing of Rosella riding upon the unicorn. You can see the original artwork here: http://ranmacmh.deviantart.com/art/Kings-Quest-IV-Rosella-461319284. She also has some fantastic Quest for Glory artwork as well! Definitely worth checking out!
