don't forget to always try to have fun when you draw. because what's the point in doing anything if you can't have fun from it?
also for future drawings...
try drawing at a really large resolution, say 7680x4320. then when you're done drawing your picture, resize the resolution down to (7680/4)x(4320/4) = 1920x1080. do not use the "nearest neighbor" method when you downsize the picture.
after doing this, the lines in your drawing should suddenly become smoother and less wriggly! this is called supersampling, which is a form of antialiasing. you can cover small screwups in your drawings this way.https://en.wikipedia.org/wiki/Supersamplinghttps://www.imagemagick.org/Usage/antialiasing/
