Jóannes's highly expressive naturalistic painting style has been described by art critic Inger Smærup Sørensen in her book on notable contemporary Faroese artists "Livandi List" (2008) as dark and discomforting, and even overtly tragic.
In summer 2007, along with fellow artist Heiðrik á Heygum, Jóannes curated and organized the largest Faroese annual art exhibit (Ólavsøkuframsýningin) at the Faroese national art Museum, which was titled "Slóarblóð" [REF].
