As a former Alabaster owner, I freaking LOVE it!!! Alabaster is one of those colors that is classy, but can be sporty at the same time since it's a non-metallic.
Before my car got totaled, my ultimate plan was to get a set of Forgestar F14 wheels, painted Alabaster with a machined face.
I think the look you have going is incredible. A drop would help, BUT I don't know how much room you'd be left with by swapping to the lowering springs on the market. In this unique case, cutting a half coil from the OEM springs might be the best bet. A half coil should only yield 1" drop... most kits on the market drop 1.4". But really I don't see anything wrong with the stance you have now.
Clear corner markers are a MUST!!!! You might even want to look into the chrome trim bits available through CTD-Germany, if you can still get them. They would really pop with the chrome on the wheels.
Again, bravo!
