This might sound harsh but i am just giving my feedback:
1. The Script is bad, even F7 Config is better, why? well many reasons with this script if you hold down space walking your mana will drain because it utilizes Q and W nonstop even if any enemy is NOT on sight that means that in F7 W doesn't activate until E is press, and if E is press and W is press then Q will be perform in F7, you will have more attack speed because W will activate attacking the enemy.
2. Sometimes just holding down space orbwalk and just taunting your enemy keeping distance you will press W and Q and if when you want to attack, then it will be on cooldown so is a lose situation there not counting the mana consumption, in other words F7 has a better logic than this script. I mean your doing it great just Don't let W activate until your Q or E lands.
3.Enemy doesn't stick, well if you try F7 and you attacking the enemy it kinda glues to the enemy so is like hits it evrytime and if the enemy takes a U turn and wants to get away the orbwalk sticks with the target delivering more blows, with the script If the champion moves another direction you will lose momentum and attacks and you will need to chaase him again.
4. Inspired last hit is really bad calculated ( FOR this champ in particular others work fine ) i couldn't get not even one CS because it will not kill them at the right timing something Inspired or someone has to fix for last hit.
5. Laneclear i like it is nice, but this can be done manually aswell.
