are you referring to the ones I posted or from the gallery in the link? The ones I posted above are just basic raw conversion. The ones in the link to my smugmug accoutn are the finished product.
However, just a few thoughts running through my head:
Winter scenes are difficult with color, they are going to be flat as it is. Try to eek out what color there is. However, they could use some more post processing. Also, another thing that has been on my mind for quite sometime after talking with a friend who is a nikon user (I notice your are a nikon guy). He stated that he always thought canon (cmos sensors) have softer colors. That got me thinking, I can always pick out a shot that was done with a nikon over a canon. Not saying one is better than the other, just different. The ccd sensor pics always seem more contrasty in general.
Enough rambling, regardless, thank you for your feedback.
