That's an excellent job, Jo, but the Powerhaul livery is way too fussy to my eye and the symmetry doesn't help here. Something more like this, perhaps:
Still too much like every other livery on the railway at the moment, though, and nowhere near as effective as the simplicity of the original Freightliner green. The best recent "47" livery IMO is the Arriva blue - symmetry not so bothersome in this case, maybe because it's broken by the branding.
