I've answered, but in addition as I don't think the questions gave the opportunity to expand. I'm not sure if my opinon counts for much as I'm no longer classed as an illustrator I suppose.
I was trained as a technical illustrator, ink pen and drafting film on a drawing board! Pretty much by the time my 4 year course was over the industry had changed and draughting rooms were filled with computers. Technology killed my passion to 'draw'.
Over the years I've stepped over lines and from illustration to page layout to magazine design to website design to responsive and app design... some days I wish I could roll back to my college years and take a different path. I haven't actually illustrated in a long time which makes me a little sad, perhaps now its not my profession I think maybe I could take it up as a hobby but unfortunately have little times for it... maybe when I retire.
