Del, in normal light, a show tan is always going to look ridiculously dark but don't worry. when you get onstage, the lights are so bright that a tan that would look brilliant normally will wash away to nothing.
Also, avoid putting any sheen or oil on large bodyparts as they will lose detail under the lights (and also don't use sheen/oil on your sides as when you come to hit a lat spread it's impossible to grip).
One tip I might offer is on your side chest shot. Your chest is actually much bigger than your pose is allowing it to be. You seem to be collapsing inwards a bit & hiding it. Stick the chest out a bit & drop the shoulder girdle (for want of a better term, relax a bit), and once in position, have both arms push slightly against one another so that the separation shows on both pecs. Here's my side chest for illustration only, I don't want anyone to think I'm showing off, it's a good demo to show the position you will be in:
