These amazing illustrated medallions are part of a personal project called "Grow" done by the German illustrator Andreas Preis. A mix of animal illustrations, mosaics, patterns and typography is what makes this projects so unique and inspiring. Take a look and enjoy this amazing selection of illustrations.
I didn't use illustrator for this. There are some minor vector graphics which I made in Photoshop. At least 95% of what you see here is done by hand with pencils and fineliners. Colors and structures were added in Photoshop afterwards.
