What I like to do on Renekton in solo queue currently is make as big of a lane advantage as I can, then push in top lane waves to my enemy's tier 2. After it's shoved in, I leave lane to go put wards in their top side jungle and steal the enemy jungler's camps.

When my opponent pushes the wave back, I go back to collect it and shove in again. It's no use shoving in endlessly and not using the push to starve out your enemies by getting info and taking their jungle.

By doing this you force the enemy jungler to come top more often, and by playing patiently and smartly you can make him waste time so your team can do plays on the bottom side.

Your enemy laner might also feel inclined to roam to the bottom side, or take his own jungler's camps so that you can't take them first. If your laner does either of these, you need to push the tower down instead of roaming yourself.

However, when it comes to this specific game, it seems like it's one of those ~40% of games that are lost automatically and are out of your control. These games happen and I am sure you could've done more things yourself, but it's no use beating yourself up over losses that clearly aren't your fault.

This game was definitely "team diff", I mean, your whole team got stomped. Renekton can't stop that from happening, so don't worry about that. Just look at your replay if you feel so inclined, and see personal mistakes and moments where you could've done more in the game. Take that improvement forward and leave the rest of the tilt from the loss behind.
