440: Yeah I really don't have time like I used to. I even found difficult to participate all competitions. However I will still stay on realistic side, but the way to present will be different. Hopefully I will have more time next week for updates
Ryosuke_Gumna, Scaff: I have used the artistic filter named "cutoff" to make separate the colour. To do this step, I need to separate the car and the background to 2 different layers. Then apply cutoff filter to each of them. (This way you can put max. 16 colour levels instead of 8.) Next is to do the outline, I apply smart blur (edge) to a copy of original image and put this layer to soft-light or overlay mode. Add satuation filter (increment) to the whole image.
There is another artistic filter can do the job as well named "Poster Edges". I found it created too many outlines for my liking, but you guys can try it out yourself.
Vonie: R32 is my favorite as well. The original image is so freaking sweet
