Stealthy Lines and Excessive Colour

For a little while I had a bi-monthly gig on a magazine all about the "Up-Stream Oil Industry" - no, I've no idea what that means either, but I got to do some fun drawings about it. Whatever "it" may be. I read all the articles I was to illustrate and thankfully was given a very good brief by designer Rob Cubbon (this is his site), but I must say the majority of what was was what completely escaped me. Fun drawing though!
