I think you'd be wise to stick with black along the horizontals of the marquee, imho. Otherwise, the cleanup looks nice!
That was a PBJ request on MK3FANs build, now that i look at it. Go back to black.
CP looks good, but i would reverse the colors of the buttons, your outlining the cab in white so highlight the buttons with white outer, black plunger.
Put the chrome dragon up top, looks weird splitting the characters, if your not gonna have the verbiage. I thought this looked good though, just remove the white dragon and maybe put the Mortal X Kombat title there.
Remove the chrome dragon from the marquee, it doesn't blend well.
Replace the 2 white dragons with chrome, leave the 2 white on top of the CP.... The chrome dragons are a little more subtle since you going with a dark theme.
