i had received some sharpies for Christmas and i wanted to try them out so i bought mixed media paper and tried them out on someone who i haven't drawn in a while (a lot of drawing i do i don't scan anymore since they're mostly to test things). i really loved how they worked especially on the eyes. i also realized that you have to work somewhat quickly to get them to blend which i found out when coloring the coat.
if you have any criticism, i would love to hear it!
