Would a CPL filter improve these shots?

Thanks, Maffer. I've ordered a Marumi DHG Super Circular P.L.D. The 72mm version got the same score (both rated equal #1) as the B+W Slim KSM C-POL MRC 72 mm in tests by LensTip.com and it's considerably cheaper. I didn't compare the detailed tests, just looked at the final scores, so I might have missed something.

Yea those DHG filters seem to be nice things. I got one Dörr Super DHG UV protector (perhaps a Marumi rebrand), don't use it that much, but it is quite flare resistant and won't turn fine detail into mush.
