I looked over your rankings and you are doing just fine, IMO. There's a marked improvement week to week on each fight.
I briefly looked over your latest H&F parse and I can offer a couple of small suggestions thus far:
Save your 2nd str pot for execute phase. As soon as CS is ready, pop all available CDs and your pot and start executing. You want to get 4 executes off during your CS window, regardless of how much rage you have left. Usually, my 4th execute only has about 20 rage available, but the first three were full 40-rage executes.
Your kill time was 4:26, which means that you had time for 4 Bladestorms without AM. You could have used BS a 4th time during execute phase while waiting for CS to come around and to get some rage up before your next execute.
Hit Sweeping Strikes before you bladestorm and make sure it has at least 6 seconds left before casting BS.
If you're using Siegebreaker, try to only use it inside of a CS window.
