Created the 3d model for the base logo on Inkscape, imported the shape to Wings3D where I setup some basic lighting and camera angles(step1.png), and since Wings3D is only a modeller and I haven't bothered to setup some rendering engine, I simply take a screenshot from the modeller and work from that on Gimp. 
On Gimp refine the lighting by adding hilights and some gradient shading and the generate the basic background(noise -> blur -> bumpmap -> perlcloud)(step2.png). Then I add some pictures of old rusty metal bars with bullet holes I shot on Suomenlinna with my Nikon D7000, shade them so the fit the style and lighting and some shadows for the logo, then gave the background nice firy orange glow.(step3.png). And as finishing touches I some shadows for the metal bars, added a picture of some welding sparks with a proper shading mode, added some crt-style distortions and motion blur to the impact point.(brc-darklite_rework'd.png)
