I am really liking the concept in #80 by using the box. If you could take out the star points in it so it is only the trails. Make the gradient color in the box black and purple (the black at top and purple at the bottom). Maybe a few more star trails and not quiet so thick. I love the font you have used and the layout of the text.
Okay... #107 1. If you could get rid of the really tall building in the center... make it about the same height as the second tallest building. 2. If you could do a silhouette of a mountain range behind the skyline and have the star trails disappearing behind the mountains. Great work!
I am liking #110 If you could make the mountain silhouette black and make the city skyline silhouette white. And make the skyline not so tall... a little bit shorter.
