Some of what I've already been doing. Making tattoo designs through collage, using popular fine art images. These are a few of my favourites. Thinking of painting some designs today at Uni on transparent plastic using acrylic paint.
Elizabeth Peyton and Paul Cezanne
Mike Nelson and David Shrigley
Designs using pencil
Here's one of my designs on Vellum Paper. Experimenting with a frame. I think the frame will help finish the design off as tattoo art. Might put a funny little line on the 'plaque' of the frame, Just to make it a little more interesting and humourous.
