reminder: tracing to learn good, tracing and saying it's your art bad
if you want to figure out how to draw something it might help to trace its shapes and construct some guidelines so you can visualise it better. once you have shapes and guidelines, reference them when you draw again until you understand it enough to not need a reference.
credit the source of the art you're analysing by the way! if it's from another artist and not a well-known series/franchise, get permission from them first you're free to research/analyse mine if you want as long as there's proper credit
anyway here's the results of me figuring out the facial guidelines of a saiki k screenshot i looked up. i traced lines and shapes over the image and reconstructed them as can be seen in the other drawings.
again: don't just trace stuff and say you drew it yourself, that's plagiarism. if you do it, do it so you can get better at drawing from scratch. repeat: it's to improve your ability to draw, do not steal. DO NOT STEAL
