After I had created my A1 drawing I then made some more in a similar drawings in an A3 sketch book.

 Although I am happy with how these have turned out, I felt that they could be improved by considering the mark making a little more. Therefore I decided to look at mark making a little more in my book before I drew any more large scale images.

 These are the marks I came up with, I feel that these marks would translate very well into some large scale work.
