More schoolwork stuff

ayyy so between schoolwork and Inktober (Yes, I am participating. Albeit I'm using a ballpoint pen, not showing my work to anyone and having missed two days as well as fallen asleep before inking yesterday's sketch.) I haven't been doing any digital aside from school related stuff and shoddy doodles

so anyways here's stuff from research class. (the first three were done from 10-12 in the evening with the help of two cups of coffee. meanwhile the fourth one was done during break, a period before the presentation hahahakms)
