With digital sketches I like to go wild with forms and creativity.I use sketchbook pro and wacom bamboo graphic tablet.It is like confidence and energy booster when I design and create something cool and futuristic.
Lately I found quick digital sketching on black canvas with white pencil inspires me a lot,then I invert it if I want to add some shading with airbrush and erasers.
Also lately I tend to procrastinate with digital sketching,because I saw many automotive designers on instgram particularly are using AI tools.I use Vizcom sometimes but only my sketches with 100% of influence to see how it will enhance it.Several years ago that platform was more user friendly for artists,nowdays I am not sure,and there is not that self accomplishment energy boost when I create pretty pictures with AI tools.
