How to draw casino art

As an artist, you pretty much just take any work that comes your way. If someone is willing to pay me to draw pictures, who am I to turn them down, especially since I, like most artist, have worked many random jobs to make ends meet over the years, and having payment from the hobby/profession that is my passion, well why turn that down.
One of my more active clients over the years has had me make them a series of casino style art drawings, which are then put into a large pool of selection that includes other casino art, and if my work merits and stands out amongst the rest, it might be used in an actual marketing campaign.
One natural aspect of any illustration work is that there is no way you will create ONE work of art and that one will be the one they used. It is always a situation where you make a large group of artworks for the client, along with other artists, and then the art piece that best matches the vision of the Art Director that is used in the end. Thankfully they pay for all the artwork regardless if they use it or not, but always more fun to see you artwork on a casino billboard rather than have it digitally archived on some server, never to be seen by the eyes of the world.
One unique aspect of art and casinos that the two share is that they are both all about emotion. Good art should have an emotional effect on the viewer, either evoking familiar or recognized patterns of emotion, or because of a subject matter that reminds them of another situation with such an emotional tone. The same goes for casinos. The reason people gamble their money at casinos is because of the emotionally charged excitement of winning and the possibility of winning more. Of course the large chandeliers at the entrance of any casino is a good indicator that they are probably winning more often than loosing, none the less, everyone thinks that they are going to be the lucky one and the process of either confirming or denying that belief is where all the fun of gambling in a casino rests upon. So the capturing of the emotional beats in the gambling world makes for excellent subject matter for artist. And the capturing of the actual emotion or perhaps just the scene is enough to evoke an emotional response in most people.
