Guessing no'one has any ideas about this then?
Well, I got in contact with the person who made that website, asking what tools he used and so on, and this is what he said:
'It's drawn in Illustrator, and I've used a 2px brush with pen
pressure. The "doodle style" was done with lots of strokes & stuff
'
Ok, so I found out, but I don't own illustrator does anyone no an alternative maybe using photoshop?
Thanks
