Your car looks pretty sick. Do you have a before and after picture of your wheels/spacers?
I was thinking of doing the emblems, that chrome piece that connects the tail lights, and possibly the front grille on my car too. We have just about the same car except I'm a grey GLA.
Love the look of your car, If you're open to suggestions I would suggest tenting the front windows and possibly tenting the reverse lights (white part of the tail lights or maybe the whole tail lights). I did a quick photoshop test below
