Just as @Aragorn stated, there's not much to go by in regards to your waist because you still have a lot of development left in you. I was going to come back and reply with more information, but he pretty much stated to what I intended. You have well developed pecs and lats and an upper back, but you have enormous potential to make your limbs pop more. Your torso dominant, which I think is actually very important in physique considering they like the sleek, top-heavy, V-tapered look, which I would never be able to pull off because I am structured like an arms-dominant clunky barrel. (I did try physique at my one and only show so far though, and came in second to a guy that looks more like you).
Also (and don't take this the wrong way), keep up to date on what's going on in the IFBB and NPC and befriend people who do what you do. That you don't know if the IFBB has a CP class when it was in this year featured in the Mr. O show for the first time, MIGHT imply one (not you per se) doesn't know what's up, if you catch my drift. It's easier to take up your lofty goal if you have the in-person, real life guidance, especially with what PED's you will need to take to excel at such a high level in the future.
And being you're so young, and while we're on the subject of PED's, I hope you are very careful and put in the necessary work before you take them: years of hard training and adequate nutrition! Realize what you're getting into when you aim to become an IFBB pro and don't neglect the other avenues of life (education, a trade) along the way.
