My technique is firstly making gesture drawings using online reference, I sketch a scaled down figure of the human model with the airbrush brush with medium size and brownish color and occasionally mirroring, I first sketch the gesture skeleton and then the body parts by using circular shapes, I usually take 5-10 mins for each figure.
then depending on the medium, I use ink brushes like This for outlining the figure, Realistic Wet Brushes if I need to do a realistic painting and Hard Rough Brushes if I need a semi-realistic, comic-like style.
as for the mindset and inspiration/reference I usually get inspired by the nature around me when I do walks outside nature or when I go seeing a ballet in a theater, taking photos (at the nature) and then replicating them on the canvas, I usually take the photos with a humble old phone and then upscale them with AI if it is really necessary.
I don’t use any plugins as for now, but might be in the future.
