im going to post the best critique I can give just to prove you wrong! More images = more fun. 
But no, on a serious note lady bug, it does you more good to post a few get some good critique and then post some more if you want afterwards either in the same post or in a new one. The reason is that alot of people skim through first before deciding whether to really respond and the more images there are the better the chance someone will keep going on to another post. hehe i guess alot of people are too lazy to write alot for each image.
Ill do my best though on the ones that are visible without clicking on link. 
Not sure what kinda post processing you do, if any, but im gonna give some advice on that too.
The first one is excellent. It is pretty dang sharp, the framing of the house by the tree on the right and by the other trees around is great. Really makes for a dynamic but not overly complicated image. This may be how the natural sky was, but it looks to me as if the sky surrounding the trees is lighter, a halo of sorts. If you feel like it I think it would maybe help a little to burn that halo area a little darker. there is one part which is flared and that cant be helped either accentuate it to make it seem like it is part of the image (easier) or try to attempt and remove it (harder imo).
I love the boxcar one as well. I think its really cool how it stands out against the bright and almost glowing snow. Maybe (if possible
) try to make the contrast of the boxcar higher and leave the snow as is. If i visualize correctly i think it would make for another super dramatic shot.
I would like the swing alot more if the strings were alot more visible. You could do this by darkening the background, or by trying the shot again and framing a little differently.
The one of the bridge would be good if those annoying branches from that are front center werent there. Hey, sometimes you gotta destroy some bushes to make the shot
The same goes for the wheelbarrow. Time to take out the machete on your next trek.
Hope this helped you out. I gotta stop typing, my fingers are bleeding.
