As I watch these roll in, I'm really impressed with your talent. Most of the ones from today though are getting the same comment. Ideally, this should look like a Vegas-strip-style neon sign. Notice that the signs in the pictures I attached aren't completely rectangular or oval. If I were to draw a line around your artwork, it shouldn't fall neatly into a perfect oval or rectangle. Feel free to be playful with the shape.
Also, you don't need a color as a background behind the words. (Color is okay in some kind of line, splash, or design element with the words or around the words -- line art, arrows, stars, etc.) The feel is that this is neon at night. You can't see the panel behind the tubes.
THANK YOU!
