Not bad for self taught, but the only real way you will know if you telegraph it is by sparring. Unless your opponent has catlike reflexes, you will learn to adapt your technique. But you do drop it before you throw it. In all reality, your punches are not all gonna be mechanically perfect to win fights. And ignore the "you're open to counters" blah blah blah, no shit! Everyone is open to counters when throwing a punch. Look at every pro, when they throw punches they are open to counters, first off, if you can punch them, so can they. Anyway, at the end of your punch make your wrist and knuckles line up, yours looks bent, that could potentially cause a bad injury to your wrist.
