A Warhammer 40k Basilisk (from Games Workshop), that I created as an experiment by the unusual method of purchasing the physical plastic GW model kit, and using nothing but a measuring stick and the Mark I Eyeball, recreated in 3D, using Maya.
No photos, no drawings, no sideshots, nothing but physical measuring and looking each plastic piece over in my hands.
It was a fun experiment but nothing I will probably do again, hah.
I will most likely end up putting it through a severe ZBrush pass and then of course, texture as better portfolio material.
