This is a digital collage I created using images from the artwork of Leonardo da Vinci. The swirls and grunge touches were added using photoshop brushes. The texture/grunge touches I used were from sanami276 and the swirls/flowers were from Yasny-Chan.



The background was an old world map onto which I applied a copper patina layer. With the cooper patina layer, I used a cookie cutter to create the irregular shape.

As a side note, I download my photoshop brushes from a variety of sites. I pay particular attention to the "Terms of Use" of all the brushes I download. If there is no "terms of use", I don't use any of the brushes on my commercial projects as I prefer to err on the side of caution.
