I posted some things in the general comment area to assist. And reranked the submissions.
#13 and
#14 seems awkward to have a square above the lettering.
I like
#12 the best so far. The overall shape is great and it feels sleek. Can you submit different versions with this in mind:
I don't like the sun on top of the doors. Maybe nothing or possible an outline of the city if it works. That may be overkill though. Nothing might be best.
I like the script writing for "The" and "Las Vegas". Maybe try some different styles, angles of italizacion and positions.
I like the sleekness of "Insiders", would like to see some other fonts similar. Also play with the spacing and size. It may be fine how it is, but would like to see other possibilities.
The underlining. Maybe try different colors or try just one line.
Play with the door a little bit, maybe different looks, or size of the handles.
Let me know if you have any other questions. Good luck!
