After taking the CG Society Hard surface 3D modelling course by Josh Herman and months of finishing in my spare time I finally completed this piece.
We had to base it on artwork from a professional 2d concept artist, and was supplied some to choose from, instantly I liked the work of Adrian Majkrzak, his work can be seen here: http://twitchfinger.com/
