The best advice I can give on this is to not listen to what people judge to be good item timings. Most people throw around the item timings that pros can achieve in their games and see these as reasonable timings for themselves. This is not the case. Pro carry players often get pure free farm in the safe lane thanks to their two supports. In some pub games, having even one good support can be rare.

Retreat

This is most often done when you're split pushing, but also if you take a tower or some situation where you find yourself outnumbered.

In this case, your  Song of the Siren, and back out or Town Portal to safety. At level 16, this spell is nearly broken for being able to split push. It has a cooldown of 60s., which nearly oincides with the cooldown of your  Mirror Image.
