Here's a zoomed in pic from the earlier one. I'll try take some close up shots when I get them into robot mode again. As for the colors I'll probably go with light grey for the red version and dark black for the black version. Mebbe it'll look nicer with another color instead of light grey for the red but to me, since its already paying homage to the G1 colors I might as well follow the trailer colors as well. Otherwise it's plain senseless to me having a train in these colors.
