Girls guarding Remilia and Patchouli should have used SBR's or PDW's since they might be shooting out the window or in the car... but who would even DARE blast Remilia's convoy when those cars roll out?
Shame Flandre is not in the picture, assuming she is in the car that Meiling was driving.
Funny you mention that - I was just about to reference this painting's "twin" with a lone Flandre and a Pagani, but I couldn't help but want to refer you to a certain doujinshi page by Imizu with Flandre locked in the back of Lamborghini ;) (although a Flandre and Meiling pair is always nice :)).
