No offense, but I personally wouldn't show a petstore VT.
Have you ever heard of the IBC? They have lots of shows in the FL/South areas. Sometimes in CA. They post their standards online, and a lot of members (including me) critique their fish using those guidelines.
At a betta show, you put your fish in a tank with all the others. The judge comes around and critiques based on even-ness of color, fin shape, and "aggression" if you will. The best get ribbons and titles. Other go home empty handed. I will shamelessly say that my fish are nothing special, either, and I would be going home empty-handed.
Try to get a flare picture of Darcy, and either post it for us to critique or to critique yourself. Then you can decide whether you really want to travel hours, spend money on live or frozen food, condition your betta, and spend hours and hundreds of dollars dedicated to the care of your fish.
Can you commit?
I know I was never able to, though I hope to someday.
