Hey all - thanks for the comments, Ed, Christel, Tali, jlombardi, Christel and Rich! I appreciate everyone taking a look.
Rich, you picked it off - I struggle with photographing some of my work. I'm using my cell phone and trying different white balance settings, which yield very different casts. Of the WB settings I tried, this was the overall best representation, but I do agree with the comments that the paper has gone warmer. I saw it, but couldn't really get around it with my limited skills working digital technology! (And it looked better than the greenish/blue tint other settings were giving - ugh!)
Tali, thanks for the detailed critique! On the right side, early on I decided to eliminate the background building and thought a couple of tall bushes might fill in some of the frame...and I grayed them over, then drew the right-side tree over them which grayed them even more. Looks like I made them unrecognizable in their final form.
The white dashes of snow on the tree are intended as highlighting only, over lots of gray and blue-gray in the tree.
I am thinking now to avoid the issues inherent with white balance on a paper that could easily be incorrectly "warmed up" like it did here, a light blue or even white paper might have been a better choice. It reads cooler in person.
My intent was to make this an overall cool scene, with the only warm colors being from the fence and some added warmer greens in the tree. To be clear, I wasn't trying for a drop-dead reproduction of the photo - it's too monotone, almost B&W, so I wanted to brighten it up somewhat.
