Winter landscapes and reflections from the eastern Sierras

Hi all

After taking a bunch of shots many looked better B&W.  I really dont know a lot of processing tricks and most of these are just straight conversions from raw then contrast and basic filter adjustments.  Any suggestions are appreciated

All shot with the D600 along with 24-85 +polarizer or 18-35 and maybe the 10.5 fish

thanks for looking!
