Self-generated artworks

Does "self-generated artworks" in the following context mean "independent and personal artworks that are not commissioned by film companies or advertising agencies"?

Context:

A similar sensibility is therefore at work in directing both advertisements and film, which is deployed through similar defamiliarising and elegiac devices in either case. (Compare, for instance, the moody skies and elegiac soundtrack at the start and end of American History X with similar devices in Twister.) Although tied to a script and ultimately compromised by the studio’s last say on the cut, Kaye’s virtuosity with the visual language is clearly imprinted on the film, just as firmly as it is on his advertisements. The question that now remains is how the sensibility and aesthetic described in this sort of work fits with Kaye’s self-generated artworks. Broadly speaking, this work has two sides: there is a body of paintings, drawings and photographs (reproductions of which Kaye intends to publish in book form) that Kaye has been working on over a period of some fifteen years and which he describes in terms of ‘diary’.
