I have had three things that made me really excited - one a perfectly straight drive that knocked the middle stump at the bowlers ebd out the ground' and my first hook and first square cut that i properly nailed. The square cut made me actually made me scream because i had been practising it with the marker then nailed it in a "proper" net.
In terms of the game, rather than being pleased with my own executions
, i think drift for the spinner - making them devilishly difficult to face - and the realisation that the timing window can vary a lot depending on the shot you play, these are what i have really thought are seriously impressive. And the whole batting control system, of course.
