The sky looks great and the colors of the sky as well. I don't really like how dark the bottom of the picture is, it bothers the eye a bit. I really do like the dried up tree as well. Good Shot.

I love this one just the way it is. The darkness at the bottom just makes the top colours pop even more. The leafless tree is fantastic. Good work.

The sky is very nice,nice silhouettes too,the photo is fine.

I like the contrast and the clouds. If only you could have positioned the shot so the dry tree was more on the left to balance the darkness on the right. Not sure if it was possible. Try cutting down the tree and moving it. :)
