i like #417 , but i am afraid people would think its a disco ball if you know what i mean, but i like how u related it with the " uned " part although it should have been more clear.
so, see if u can work on it to make it more elegant and doesnt look so disco ball with the small blocks in it, see what you can come up with else
your other entries, i found them normal and didnt stand out much, look at the top 8 and have something creative, yet capture the overall look and feel of there strong and good use of colors and effects
