They are clear and the lighting is decent. However, I’d watch the composition.
I like #1 because its clean looking. Although the surrounding area that fills the rest of the picture is a bit blah to look at, but overall, not too bad.
#2 has some nice facial expressions, good job capturing those. Is the post normally crooked? Maybe getting him a little further off the post might have been good for the composition, kinda like how she is. I dunno, just some random thinking.
#3 is a great idea and I can totally see what you are going for, but again, I think there are some minor composition issues that should be tweaked. For starters, he has a tree growing out of his head, giving him a weird reindeer look. They both again have great expressions, and I like the use of the fence. Maybe moving in a bit closer to cut out some of the sky in the background, having them a bit more in the lower right hand corner (just a bit) so the fence might lead your eye towards them, instead of them mostly in the middle of the frame.
