i personally disagree with a fewparts with the statements made above
considering the thread is named traditional art, im assuming you're wanting to get better at it. whether or not you want to take it more seriously in the future, (not saying you aren't now), im gonna give ye cnc on what ye got here
transitioning to digital art because you are unable to do smooth pencil strokes is probably the worst thing you can do imo. dodging fundamental basics will hurt you farther down your art path. video tutorials are great sources of inspiration, and while its paradox you can copy certain art styles if you so choose to. however you will want to get out of your comfort zone at some point to grow.
tl;dr
do what you feel is right
a simple way of improving stroke smoothness is instead of drawing away from your body, draw the line towards you. You will find drawing the line towards yourself will be much easier. Using purely your wrist to draw lines will usually result in a curved line.
tl;dr
dont be afraid to move your arm
when drawing eyes dont forget that they are actually just balls. Learning how light affects certain shapes, (cylinder, cube, and sphere are good ones), will greatly improve your ability to draw shadows. concerning the eye, no matter what style you are going for, the top of your eyeball will USUALLY be darker than the bottom. this is due to eye lashes, eye socket being a bit deeper in the face, forhead protruding a tad, etc. also common light sources are usually never under your object, (unless ur going for some mysterious spooky look.)
overall this is a good start. many simply dont feel like drawing and only think about it. double props to you posting it online for people to see.
hope this helps ye out
