Not sure if it's years and years of mx or just how i ride
I'd go with the years of motocross, it looks like your sitting up and pushing the bike down, all you've left to do is stick your right leg out
The track day schools teach it how Donsy says, keep the bike as upright and on the thick of the tyre as much as you can, so hang off the thing like a demented gorilla.
I see the photographer has also tilted his camera, it give the effect of you leaning it over more than you actually are and so looks more dramatic
This is me some years ago at Pembery in Wales the left picture looks like i'm going so much faster and with more attack than the right one
