Old Tails Medallion

Please meet Miles "Tails" Prower, Sonic the Hedgedog's best friend!
Old version of Tails

Created from an image, I made a vectorial drawing that I have extruded with CAD. The piece fit approximately in 30mmx30mm (1.2"*1.2").
This piece is part of my medallion collection, which can be fully viewed here: https://www.thingiverse.com/Silvood/collections/medallions .

Artist for 2D Drawing is unknown :/
