So I took a look at the game from the final screen and feel like I may know why you lost. Correct me if I'm wrong, but that Nasus had a ZZrot portal and was probably constantly keeping waves and pressure on different sides of the map.
I'm going to give you some advice, I checked the rank and it said you were Silver 5 and a Jungle main. Nothing wrong with being silver, and if you are a Jungle Main that's GOOD, you have the power to dictate the pace of the game, and I've got some advice on how you can do that.
The way that things work this season is that everything is always on a knife's edge, 1 bad fight even when ahead can mean a lost game. And games in Bronze-Plat are a constant clown fiesta. So here's my advice, tell your team in champ select you need at least 1 champ with Waveclear, (Viktor, sivir, etc.) if they don't listen then it doesn't matter, because you are going to focus on yourself and how YOU can win the game. My best experiences are with champions who are great deulists like Jax, Volibear, or Hecarim. Now know something, you decide how you want to jungle or lane, don't let your team berate you for choosing to not do something that could cost you.
Ok, now here's the secret to dominating the game, it's Pressure. If you have a lead, you push that lead (calculated pushing, not blind over aggression). Get green smite or sightstone and light up the enemy's side of the map if you are able, you always want to know where people are. Now look for any opportunity to take a tower from the start of the game, if you kill a laner and they don't have tp, you smack their tower, proxy farm if it's safe or you have backup to fight between turrets, and repeat gank/roam later to take it if you need it. Everyone asks what the best champs to carry are, I firmly believe that the best champions are ones who can take towers quickly and fight in a 1v1 scenario.
A great way to influence pressure is Wave management, which is basically keeping waves off your turrets and pressing them onto the enemy's side of the map. It's like a safety net, that way if you do lose a fight you minimize the amount of resources that can be taken from you. Wave management deny's rotations, let me give you an example: Your team loses 2 people mid lane and someone has to base, and you have resourses to defend mid lane but a wave is crashing into the top lane so the opponents grab that turret instead, that's 800 global gold that could have been prevented if the wave had just been pushed out and your team would have had time to regroup. It's such a small technique that people just never seem to utilize. Even as a jungler, do not be afraid to move into a lane and push a wave into turret if the enemy is gone. You want those turrets to go down so you can open up the map, and if you want to push even harder get a 
. That item makes it so you always have a lane pushing and putting it behind a tower being sieged on slows the enemy drastically, it's so fucking good.
Now this last part isn't hard to do but it's all on you, make good decisions and just look at the map every now and then. Recognize where you get the opportunity to push waves, deny experience, or counter jungle. Try to always know here the enemy jungler is, I personally love smiting their wolves if I can safely do so to see if they come into their portion of the jungle. If they aren't near I try to sweep dragon and solo it if I can. Really what i'm trying to say is focus on how you can build your own lead over your counterpart; if you farm correctly as a jungler you can be level 6 less than 7 minutes into the game. That's a huge powerspike considering i've seen junglers hit level 6 at more than 9-10 minutes into the game.
This is just some advice I threw together for you on how you can look to improve your own play, just focus on improving yourself, play the map, and take time to untilt if you have a bad game, because every game you go into is a different one. One more thing, if you take an inhib and have outer turrets left to take, don't just "Run it down mid" that is the dumbest thing you can do and I see people even in Diamond do it (I am part of a league club in college and even this one guy in challenger does it all the time and it tilts me watching). Look to group and take turrets or bait fights around baron/dragon especially if the enemy lets super minions onto the nexus turrets. If you have any more questions or concerns I'll try to answer as best as I can, because i'm really trying to help.
when he belongs in bronze 3. just becuase no one has the skill or teamwork to stop Yi until silver.
