they didn't take my application, but I like some of the stuff in this teeth themed portfolio.
These depict the life phases based on teeth. In German particularly the false teeth are called 'third teeth' or just 'thirds' („die Dritten"). So these are named 'First Teeth, Second Teeth, Third Teeth'.
They were done on ivory coloured sketch paper with lead pencil and neon yellow (highlighter) coloured pencil. For online display I edited the colours, because usually highlighter colours lose all their brilliance when scanned. No need to explain that here, hm?
