I don't mean that in an offensive way, please do not take it as an insult. What I am saying is that we all have our on ways of doing things in different forms of art style. Tracing can help you become a better drawer quicker, because you'll be able to better understand the outlines and shadings of what you're drawing, however others may prefer a more harder accomplished form of working with art, such is myself. So please do not take it as an offense of what I'm saying, mean it more in a complimentary state. ^^
It's ok
