As a grade seven student, I may sometimes talk about art even though its a subject in school. If you're trying to dray something, don't print! Sketch first so you can erase mess-ups.
I like your tip! I totally agree and think that you should sketch a picture before doing a final draft. I guess it's like anything really. You should do a rough draft or several drafts before completing your final draft!
