Couldn't resist having a play in the end

1. Download image from net and into gimp, added alpha channel.
2. Duplicated layer so I have three layers of the same image.
3. On bottom layer opened Gmic and went artistic>cubism, ran on default settings.
4. On middle layer opened Gmic and went artistic>dream smoothing, ran on default settings.
5. Still on middle layer added layer mask, made sure layer mask was selected and went filters>Render>Patterns>Chequer Board, changed size to 1 and clicked ok.
6. On top layer opened Gmic and went artistic>Rodilius ran on default settings.
7. Still on top layer went layer>Transparency>Colour to Alpha and changed colour to black and clicked ok.
Ideally your image needs to be on a black background so this might require cutting out the main part of your image first and pasting onto a black layer.
