Really good job following the soldiers into the backlines of the last push around 25:50, it was a really good catch, but they were both shut down and you covered it well enough. I would've probably tried to match the hype of the demoman single-handedly knocking them both out, but otherwise really good eye for following the action on the last push.
When it comes to covering a backcap done successfully, the words "did tibby cap accidentally" don't come to mind. While it's crazy sometimes when a backcap is pulled off, try to use some other words to describe it.
Around the 28 minute mark after the medic on red drops uber, you kinda go into this state of delirium covering the sack attempt by Walrex and AAAAAA, which really doesn't fit the action. Maybe I'm polarizing it too much when I say the words have to match the tone of the game, but covering the bomb from walrex or the in-your-face shots by AAAAAA would've been good, rather than focusing on "I was right! Liam died first! Mwahahahaha"
When liam kills the medic somewhere around 30:55, I found it funny that you said "liam finally gets a kill for the first time" which while it may or may not be true, is kinda bully. You can make one-off comments if you want to, when talking about a player, but focusing on how bad someone is playing detracts from the commentary.
Awesome job at 31:30 predicting the flank from alley, and the absolute destruction of the team capping the point. This was well commentated, both in prediction, and when it actually happened the "oh my gawwwd" at the despair of blue team getting mulched. Very nice.
While the scoreboard can sometimes speak truth about how well someone is playing (single digit points for liam), saying a demoman sucks because he's at the bottom of the scoreboard also isn't verifiable (especially since I remember him pulling off a solid defense against the blue soldiers). You gotta use your memory within the scope of a match to decide whether or not someone is performing well or not, and scoreboards should only be supporting evidence of that, rather than acting as the truth of their talent.
You kinda went silent during the red push into last around 33:20.
And the next red push into last around 40 minutes.
Overall your energy is kinda all over the place, I do think matching the pace/tone of the action is what makes a commentary really good, if a frag surprises you, share that expression. If a play is absolutely amazing, let your commentary reflect that.
Thanks for sharing
