this is incredibly cool. i love the bumpmapping. you are such a pixel monger it blows me away when i see this and know you did it only in photoshop. it looks so much like pixel and your deep pc underground roots shine through. rocks man. the only suggestion is add some color to sparks. you, like myself, usually do monochromatic coloring when it could benefit from some stylistic color choices. especially on the sparks.. bright orange, yellow or blue, with maybe a flat reflection on the logos underside..
