Above are two drawings I created for an assignment within the anatomy course of my masters program. The drawings of the feet were done with graphite, based on photography of my cousin Oihana, a professional ballerina. I added color pencil to illustrate the muscle and ligaments.

Above is an illustration that was made into a ceramic plaque for the lentisk tree in the university's arboretum. The illustrations were drawn in graphite and the text and icons were added in Inkscape(a similar program to Adobe Illustrator).
