Help! New to graphic design

Hello! I am brand new to graphic design, so far I’ve used paper, or handmade canvas to paint/ draw. Type of art I’m used to is water colors, sumi ink, abstract and detailed drawings.

I am needing a REALLY good stylus pen for my touch screen laptop. Something that can accommodate what I’m used to, i.e, fine lines, tiny details, big sweeping brush strokes

I’m working on a childrens novel and it would be easier for me to do the artwork on my laptop.

Any and all information would be greatly appreciated, along with any tips

Thank you!
