The first one is very cute! I like it. The second one is nice. The third one is ok in my opinion. I like silver lined clouds like the 2nd but regular sunsets like the third one isnt very interesting to me but I know it's pretty.
You can totaly experiment with the first one. Add a stick somewhere, have someone doing the 'first shot'. Move the ball further away (it might make the image stronger. It's hard to tell because the picture takes up lots of room on my monitor and I have to scroll around to see all of it)
