Is there a word for a thing that is drawn?
"subject" .. as in, "I will be drawing three subjects, a rock, a tree .."

OR (reviewing this caused me to think further about other possible answeres)

"i will be drawing three objects, an x, a y, and a z"
OR
"I will do a drawing of three objects, an x, a y, and a z"

I still cannot think of any single word for a drawn thing
