In a dynamic return to gross, cold-ridden sniffling form I lead you by the clammy hand through the introductory skills of bringing a scan into Photoshop of your sketch (well my sketch), tidying it up, and giving it some monochrome depth to make it POP off the page.
This is a great technique to add some value to your sketches without breaking into a sweat - with your own sketches your action should be fast and clear, I was a bit ill when I recorded this so you'll have to forgive me, I know you will.
Give it a go, have fun, work fast and good luck!
