I struggle with getting mine synetrical as well, and i've come to the conclusion that it's so hard that it's near impossible. To be honest, it doesn't look too bad in your photo and i doubt many people would notice (if anyone at all!) Even the model's isn't 100%, and he likely has a professional stylist tidying him up before a shoot!
If you're really set on geting it perfect though, i'd take a tiny bit off the top of the "thicker" side to narrow it down a little. If you're feeling brave, you could even pluck (not much though, just 2 or 3 hairs deep.) I don't think it's the tip you've circled making you think it's off, more the other side just being naturally deeper.
