Environment illustrator: what is needed?

To be an illustrator of environments you need to first know how to draw or have notions of perspective, then to be able to manage a drawing program on the computer or maybe you like to color on paper, but regardless of this you will need a scanner or camera to convert it to digital also for It is to print as is this case.
I specifically needed:
A mechanical pencil of 0,7 mm (+ 2 mines nº H)
An eraser
A computer
A Scanner (to scan the sketch in pencil)
A printer (to print the pencil art in blue)
A marker of 0.8 mm
A Wacom tablet
A box of beer
Software: Adobe Photoshop & Adobe Illustrator
