[2] His art consisted primarily in imaginative pen and ink drawings and batiks inspired by his country's wildlife.
[3] In the 1970s and early 1980s, Akis divided his time between subsistence farming in his native village and working on his art in Port Moresby.
[3] During a posthumous exhibition, the Tamworth Regional Gallery (Australia) identified Akis as one of Papua New Guinea's leading print and drawing artists, along with Mathias Kauage, John Man and Martin Morububuna.
[6][7] An exhibition in Cairns that same year celebrated Akis' "international reputation", along with that of other notable Papua New Guinean artists,[8] and his art was also displayed at the Alcheringa Gallery in 2007.
[12] Akis' art has been featured in the book La peinture des Papous,[13] along with that of Mathias Kauage, Jakupa Ako and John Siune.
