I do! 
Really, there's nothing bad about any of these, but there is room for improvement, I think.
[1] This one is really dark in the shadows, that may have been your intent, but to me, it doesn't add anything positive to the shot.
The square crop doesn't help this, in my opinion, it seems slightly lacking, like it needs something on the side, I am a BIG believer in The Rule of Thirds
though. I agree that this stump is really something, but for me, as it is, it doesn't feel print worthy, with a little work, maybe. The lighting appears too harsh, which you can lighten the shadow areas if you know how. The crop, if you have room, needs to be adjusted, adding (preferably) to the right side, because for me, the lowering slope of the mountains calls for that. I don't know what side you have to do this though, if you have any wiggle room at all. For me, it's too tightly cropped on the top and bottom, I'd give it some more room at the top.
Either your photographer's 'eye' was off on this, or your cropping skills need work.
[2] The image gives me a feeling of drabness rather than what it should, the snow you shot was possibly blown out and you tried to fill it using Photoshop or similar program to make up for it. That is possible, according to the image, and one's skill level. This is more dreary this way, and doesn't work at all, I mean that in the helpful way, it's not crap. heheheh
Some things can have 100% white in them, the sun, glare in water, and metallic objects, most anything else like snow, it doesn't work. Blue snow that we tend to see is a camera thing, we never see blue snow in real life, we do see blue in icebergs though. Yours is on the yellow side, which can happen, but only after wolves and coyotes have their way. heh
What you need to do is learn how to better color-correct snow, and images in general. If that means going to YouTube and typing in, "Photoshop color correct", try that. You may want to go to http://www.lynda.com and take their video courses, which are really very good, and very inexpensive.
There's a bunch more, do a search here for photoshop courses, I am sure there's many.
The only nitpick I see on this image is that you cropped the tree off on the top right, if you have room, let the top of that one show.
Your 'eye' on this one is not bad really, it's mostly your Photoshop skills.
[3] Not only do I love this shot, I am envious, I wish I could catch a coyote in a pose like that, I love it!
What I would do to hopefully help is, if possible, crop off the left-hand side, and open up the right side. Hat will balance the shot to make it more visually appealing to 'most'. I say, "most", 'cause like I said, I am a believer of "The Rule of Thirds".
Sometimes The Rule of Thirds can be broken, it's not a law, it's just a general go by, so you can always tell people that like it to go somewhere. heheh This one, in my opinion, needs that, but, if you don't have the side room, and you like this, maybe try making it a vertical looking shot, meaning making it slightly more on the left, and less on the right, and maybe that'll work. The color seems O.K., it could use some very slight change to the blue cast of the snow, but it's generally good overall.
This one has a good 'eye' for the most part, if you agree with The Rule of Thirds after you read about it, and want to practice it, it'll help you out in the future.
[4] This one's about the best of the bunch, I like the coyote better, but your 'eye' shows here, it's a pretty good shot, and most people will like this one best, I'd think.
You could punch up the color slightly, but mainly, what stands out to me is the crop. Again, The Rule of Thirds, if you had more at the top than the bottom, it's be better balanced. You almost have it perfect, so this is kind of a nitpick for me. All it is, you seem to have it 'too centered', it would be better off if you did the above.
All in all, I think they are pretty good, but to print them before doing some of this may not be a good idea, (if you agree) that's what I'd do.
If you like them, of course, print them, but if people see them, they may think some of the above, if they know photography, people that don't know about it will probably not notice.
I say ALL of this to help out if possible, I don't mean it to sound at all harsh, that's not how I talk.
To my knowledge, laptops are not what you want to color-correct from, or so any Photoshop stuff from. You can get a cheaper (good) monitor and do stuff though, it's only the laptop's screen that is (usually) not so good for stuff like that.
