A quick concept design sketched using the Artstudio Pro app, on the ipadpro + apple pencil. ArtStudio Pro for me is hands down the best drawing app on the ipad atm. I've used procreate too, but there are way too many gestures to remember, and being able to also use a bluetooth keyboard in ArtStudio, you sometimes forget you're not using photoshop.
Full process sped up to 1min. Original time is probably about an hour.
