how to be good on estimating the arrow of mirana when we are nearly hit or when we will hit someone...

Try to take their MS/escape routes and such into consideration before firing. And never target the guy your shooting, click the ground in the right direction.

Ingolf made pretty nice potm guide, hope it helps " http://forums.dota-allstars.com/index.php?showtopic=217572 "
cheers!

Try to find a good angle and don't shot from the side if you don't have too. Allways easier to hit the enemy if you shoot him straight from behind, infront of him or diagonal from the back/front.

The rest is just practise practise practise. The more you play the better feeling you get about how far the enemy has run in the fog of war.

Predict their MS and situation, which ways they can go or which way would YOU go.

i just fire the arrow when im sure!! especially in the clash!! but still i fire when gankin!! and also in blind spot!!!
