After submitting a number of dev and scraps, I realized.
My scans suck.
I dunno whether it's because the scanner is in the fritz or I scanned it in low dpi.

Ah well. I'll try to re-scan if I have time and willing to do it all over again.

Got a lab report coming, some quizzes this week, also going home for a week or less during recess.

Nothing to do.
