For my pen drawing of a PS4 controller I used a black biro pen. First I drew the controller in pencil lightly so could get the shape and the details such as the buttons in before I would go into using pen as this allowed me to rub out any mistakes I have made to it, as doing it in pen will leave permanent mistakes and I’ll have to start over. I used the cross hatching technique to get the pattern on the bottom parts of the controller, I layered this to get it to be darker, I didn’t do the lines too close together so that I wouldn’t lose and details because of it being too dark. I also used some contour hatching around the edges to get them a bit more darker because of the shadows that was cast on them. For the main part grips of the controller I used a different technique this time on the outer parts of the controller to give it a softer look fading from light to dark, the light hitting the controller almost head on. The technique I used is called scribble hatching.
