though i am happy with this illustration, i have used the map illustration on another illustration therefore didn't know weather i should try and experiment with other elements to include on this drawing. 

i have played around with adding the layered collage of the heart shaped map outlines i have done earlier on in my practical experimentation. i like the way the map outlines a negative space of a heart right where the heart exists on the human body. however i thing the shape gets lost the bigger the layers become which makes the point un-obvious. i also don't like how the map layers hide the scars on his body i have draw as the whole reason i have chosen to drawn this particular drawing is to show his scars.

keeping top idea;

reiterates the point of the bob graham route, like how it looks likes a follow on tattoo or even vein like.
