Hi Lisa,
This is really nice! It has a wonderful hand painted feel to it.
The fence post doesn’t bother me either, but if you want to remove it, it is plausible to have shot the scene between fence post since there’s only one anyway (in other words, there could be a post on either side just out of the frame). Only problem would be that the fence wire goes to a slight peak at the post and that “might” be noticeable to sharp eyes.
Otherwise, the image seems too bright as @David_Bostock mentioned, I think you’re losing depth and definition at this level.
I’ll have to say that the color in this is awesome to my eyes!
I used the exposure mask in Ps for the edit below, I lowered the exposure to -.30 and increased gamma to +.70 (no offset)
I think that the adjustments added depth…and definition to the scene but that’s just my opinion.
Literally everything else in the scene is great including technicals as well as aesthetics IMHO. 
Note: The edited version puts the brightest looking white parts at 220. (red 220, green 220, blue 220) which is nice pleasant brightness for scenes with snow in my very humble opinion.
Edit:
Hi Lisa, I am really intrigued by your IR image, it makes me want to explore the idea of trying it out myself.
I was up at 4am and needed something to do so I decided to see what this would look like without the fence post and maybe even remove the stray branch at the post as well, after that I decided to try adding a very slight amount of Orton Effect to the highlights in the trees. If you’re not familiar with the Orton Effect, there are several methods demonstrated on YouTube.
The main thing here is that it’s only ideas for you to consider, use any of it or none of it.
The only thing I feel needs addressing is the brightness and even that is just my personal opinion.
I really hope you don’t mind me exploring ideas and posting it for you to consider.
To further state my interest, it isn’t just the IR that intrigues me, it’s also the scene you have so wonderfully captured!!
Love it 
BTW, I don’t think anyone will notice the slight arch in the fence wire unless they are really looking for it.
