He graduated with a Master in Fine Art degree from Rhodes University in 2011 where he majored in painting and participated in the Visual and Performing Arts of Africa research group. His MFA exhibition, ALIEN-Nation (2011), considered themes of xenophobia, foreignness, alienation and stereotypes, and explored the complexities of the Nigerian diaspora. The process of working in a traditional studio portrait manner was integral to Makun's work in this particular exhibition. Makun has exhibited extensively in Nigeria and group shows include Romance with Iliad, Wangboje Gallery, Pees Galleria (1999); Women and War, Goethe Insitute, Lagos (2001); Colours of Life, Nicon Noga Hilton, Abuja (2006); International Art Expo Nigeria, National Museum, Green House Gallery (2009); and Treasures of Benin, National Arts Theatre Lagos, Nigeria (2009).
