I like the livery itself, much better than that rotten old commuter livery. The yellow front could've been better but overall it's okay. It highlights at how little glass there is on the sides of these units though; a few small windows down the side. Don't strike me as particularly bright and airy.
Also agree about the modern British liveries, apart from GNER there were very little if any I liked. Virgin is okay but not much after that. The freight company liveries tend to be much better.
