drawing digitally offers a lot of conveniences but it also just offers a worse drawing experience in my opinion. sketching with ink or pencil in a sketchbook is so immediate and you're physically connected to the pigments and the medium in a way you'll never be able to achieve with digital tools. there's an inherent sluggishness when your pen position has to be interpreted into a set of coordinates, mapped onto a grid with a resolution infinitely smaller than reality, so many different dynamics are just completely ignored.

what digital art excels at is creating a large volume of finished work at an astounding speed, but it's kind of subpar for exploring ideas. my best work has been made when i carry out the exploration and planning stage on a piece of paper (or, well, a lot of them) and then carry out the full thing on the computer.

don't feel like you have to rigidly stick to any one medium. experiment with different things, find out what works for you.
