Logo Work. [Work in Progress].

As part of our book proect, I thought it would be useful to develop some sort of logo I can use for my works.
Seeing as I was using 'ADGD : ALISON DOYLE GRAPHIC DESIGN' as my header for this page before I replaced it with the current banner, I thought I would work with that abbreviation and play with it.
These are just initial sketches to be furthered on illustrator and the like.
