HELP - Step by Step guide to convert photo

[Grump]

Hi everyone,
I have an original photo and need it converted in the style of Shepard Fairey but to a more colourised version. 
Can anyone provide me with a simple step by step guide, PLEASE?
I would be most grateful. 
Thank you.

These can be vector or almost vector creations and starting from a photograph will very much depend on the photo.

However, without knowing the starting point I might do.

Make the photo more dynamic, this using the retinex filter Colors -> Tone Mapping

   

Then reduce the colors Colours -> Posterise

Another day, another type of photograph.

This one I might.

(1) Remove the background. Many ways of doing that, I used the Foreground Select tool. https://docs.gimp.org/3.0/en/gimp-tool-f...elect.html

   

(2) That gets copied and pasted as a new image. Edit -> Copy then Edit -> Paste-As -> New Image.  A bit on the large size so it is scaled down  Image -> Scale Image.

(3) I want to make that look Vector-ish, Simplified shapes, defined edges. Using a plugin gmic_gimp_qt. There is a Windows Gimp 3 plugin installer http://www.gmic.eu

   

(4) Many have a sunburst type back ground. Added as a new layer under Layer -> New layer and again using the gmic plugin - the rays filter
