Need help with Irelia matchups

The video provided is me vs Shen. You'll hear a lot of chatter between our adc and support bantering back 'n forth. We're all gold minus the support who's a plat 5 I think.

I'm trying very hard to overcome Irelia's toughest matchups. I do this by watching Irelia Carries U quite religiously, the only problem here is that ICU is a bit unrealistic; I only see the games he pub stomps vs the games he struggles and maybe give us insight as to why he struggled. Which is fine, but I feel like I shouldn't be struggling with Shen top as much as I am.

So far the toughest matchups for me are: Shen, Trundle, Darius, Garen, and Nautilus. I'm getting better against Darius, Garen, and Trundle, but the other two I feel like i'm making little to no progress. If you could, please watch the laning aspect of the video (or the whole thing if you want) and tell me what i could be doing better. Farming is always something I could get better at, so anything besides that if you don't mind. You'll see me miss a few easy minions, and you'll here me getting disgruntled (lol). It goes without say that I miss easy minions due to either getting distracted by something, minion collision, or misjudging the timing of the last hit.

If need be, I can post up a video against me and a Trundle where we BARELY win the fkng match. Sheesh. Lately, I've found against Trundle that if I buy Executioner's blade early, I can trade much, much better, but it still is a hassle late game. Any help is appreciated. Thanks in advance.
