Hey Everyone, i created this model last year by following tutorial because i was new to hardsurface modeling and i did only modeling and texturing, didn't rigged, animated and composited. Few days back i found this model in my drive and decided to finish this piece!
Things i learned in this, rigging, parenting objects and animating it. It was fun animating this, will share some other animations soon.
Thanks to @RyanKingArt for wonderfull tutorial.
