>>1011294Not really, not only is it 100% unnecessary for that example in particular buy it would be MORE work, hassle and time spent for a painting that looks like that.
I know you dislike artists or something but you should listen when they tell you about something they do every day (digital painting)
Or you'll end up like this guys who legitimately thinks a photo the base, or that photographing a person would result in that shape more easily than just outlining it and filling it in paint.
>>1011304But he's right a bout collage-ing textures from photos, for example, they just cut the ears from a stock photo, you can cut the stubble and clone-brush it in, In both cases this is something you do TO YOUR PAINTING, the painting and blobs are the base, and details like the meaty cyborg parts, the scars, and hair are 100% hand painted.
There were no magical cameras that produced that flat map looking image from a model, and if they did then they would MOT look like the example, where the ears are just pasted in with minimal blending, then the skin would be continuous and transition naturally all the way to the chin and back to the other ear, instead of being airbrushed and none of the shadows would look like that, specially around the clearly painted nose, they just had rando skin details and clone brushed them where they felt it would help.
