Seinfeld Neon WIP

I've got a lot more ahead of me with this such as making it all glowy, adding shadows and textures, etc.

I'm wondering if I should fill up some of the negative spaces? Especially around "OF YOUR"? I'm also playing with the colors still. I'm referencing a bunch of neon and it all looks so simple, but then I try it all and nothing looks right. Thoughts and suggestions are wanted and appreciated.
