Done for the "Industrial Design of the Week" competition at ConceptArt.org

So first i made a buncha sketches on my sketchbook... then i picked one and rendered a sideview of it.. then i used that sideview to make a 3D sketch model.. picked a nice angle and switched to Photoshop... Refined some parts, added a lot of details.. bla bla bla... and heres the result..

Here is the basic 3D model: http://dekus.deviantart.com/art/My-tank-concept-72618254
