Yo...
This is actually an old sketch of mine.. just found this out in an old sketchbook and decided to render it..
Started to render on a Creative Workshop we had at a frineds house where we played Left 4 Dead, designed textures for his spaceship, and drew a little.. bla bla..

Photoshop
Wacom
Dunno how long this one took me... maybe about 7-8 hours.. ?
No reference..
Title by my friend ~Cytron

I guess my inspiration was the Heavy Fuckikoma (or how the heavy one was called..?) from GITS..

BTW.. if you think "hey! spiders had 4 legs on each side.. this one has only 3..." there are two little legs at the very back of the tank.. in shadow..
