Here is my PaperZoo project.

The backgrounds were created in groups using water color paints and was scanned in at 300dpi. The animals were hand drawn with references to the internet and then also scanned at 300 dpi.

Using Adobe Photoshop, the animals were then placed on top of the backgrounds and then blended in with the multiply tool. The PaperZoo logo was provided by the client and the text of information was taken from Wikipedia.
