Hello Tom! Welcome back! Here's your goat for the evening!
oh and here's some critique to go with it:
*contrast! just add 20 more contrast to this in photoshop and it's much, much better. the darker become darker and your highlight becomes pure white (which is good, for metal)
*I'd lose the dithering, when it comes to metal, personally. That's when you either add shades, or do some sort of cell-shading sylistic trick. Dithering suggests texture. Metal doesn't have a rough texture.
*some jaggies on the black outlines
*not enough goat
