I am just wondering if anyone would be willing to list pros and cons or their own personal experience would be better. I ask as I am very artistic. I have plans of doing sketches for some of the unusual technology in my alien based book however I do not see sketches included in mass published modern books - some of the older books obviously had sketches / drawings included in the margins. Is it possible to include sketches in actual published work? So again if people could give their thoughts on either that'd be great.
