I need art tips :)

So hi everyone,
Guess what? I managed to afford a new pen for my laptop! Good job to me :smile:
I’m only starting out with episode art so I just need a few tips: ESPECIALLY on drawing like details in a guys hair, because it’s confusing the heck outta me.
Thanks :two_hearts::sparkles:

What program are you using? And for hair in general, make sure to add different shades in the hair along with highlight wherever the light source is!
