Looks good, any thought to blacking out the grill?
Might help to tie together the "murdered out" look
I think from an artistic viewpoint...the Mocha has huge contrast to the black
The tinted windows definately help to tie it together
Black roof rails and mirror caps might be a good idea to consider next with the grill to help with the blacked out rims...and blend everything together a little more.
Maybe play around in photoshop to see how those items might look (?)
