Do you like the yellow c and orange d or should it all be orange?
Try fading the C from orange to yellow... bottom orange, top yellow... Do the opposite for the D... top orange, bottom yellow... and add a small shadow under the arrow, casting onto the D. Only onto the D, not onto the background... Unless you use a 10% shadow for the whole logo, floating it off the background. Shadow set bottom-right side. (A 20%-30% shadow, not dramatic, just enough to expand the contrast.)
P.S. Use softer metallic texture... mix a blur 25% and that texture, for a softer look. That or just tune-down the contrast on the metallic texture.. Also add about 1-3% random noise in the lettering. Makes it look less computer generated and adds a more natural grain. Only like 1% noise to the whole image, to wash-away any shade or color-banding you get on lesser quality displays.
Possibly also a super soft shadow from top to bottom, linear, to add some depth to the whole image... possibly with a faded void randomly sliced through the top-center, to give it that semi-plastic-coated look. Just enough to remove some of the flattness.
