it's looking good with a few minor things that could be changed in a jiffy.
The metallic part should have a more brushed metallic/silver color scheme. right now it looks a bit more light blue than silverish...
also looking at a USB tip that i have i saw that the white part on the inside continues onto the front of the usb. in the picture the front part is black, but maybe should be white?? correct me if i'm wrong though i'm pretty sure not all USB connectors are the same
Like i said these are minor things and the mesh looks in place. Wouldn't mind seeing a shaded wireframe shot.
