Using a bold black background we are losing infos, which we could have seen if there is a transparent background.
I already criticized the search icon with the marker inside. On the black background it works even worse for me. The search icon for me looks no more like a pan with one single fried egg in.

Alll in all I'm not so sure if we really need a complete new icon set. I looked at the in app icons and they looked to me quite consistent. Only the Center Map Icon in the menu looks somewhat unfitting. But
as you already pointed out we don't really need that in the menu, it is enough to have it in map view.
