Almost a minute in, and I still can't tell the meter of this piece! Mixed meter works to keep the listener completely compelled, as it doesn't let them get comfortable with a beat. The otherwise straightforward harmony and unchanging accompaniment results in something rather trance-like, which works well for the context of a casino. I wonder what you could have come up with creatively to tie it more into the theme-- yes, most pieces are a glimpse into the composer's personal world. But how could you have tied it together and made a story about 'entering into someone's world' in a unique, personal way? Regardless, nice work, and keep writing!
