These are general writing comments rather than concept ones. If you'd like to talk concept, we can do that, but I figured that's a separate discussion. 
As a disclaimer, most of what I write is boring non-fiction, so take my advice with a pinch of salt, etc.
Speaking from that perspective, I have one point here. You might want to consider doing an editing pass for flow and readability.
One old trick, used especially by broadcast journalists, is to actually read out what you're writing. Read it out loud. If you don't want to pretend you're a news reader or audiobook narrator, then at least mumble or mouth the lines to yourself. This helps in figuring out where to break up sentences, or where the natural pauses might come in. This is crucial when writing actual spoken dialogue, but it also helps improve clarity of third person omniscient narration.
There are automated tools which will rank your writing on a 'readability index'. Of course, automated ways of calculating this aren't a perfect gauge. But, at a glance, there's areas where you could use more commas to break up sentences... or places where fewer commas may be better, and you might instead want a longer chunk divided up into shorter sentences.
Increasing how 'cleanly' your prose reads will go a long way. For many people, the mechanical flow of the text is what they really notice, not things like style.
Issac Asimov once wrote that if you need to describe the sun coming up in the morning... you write 'the sun came up in the morning', plain and simple. Maximum clarity. You don't want the reader to get bogged down in fancy language or structure. He even argued that writers should avoid using metaphor and simile where possible. Of course, even Asimov didn't strictly follow his own rule, since there's definitely examples of lyrical language or descriptions in his stories.
Taking off my professional hat and putting on the 'shitty fanfiction author' fedora, looking at it from a fiction perspective, I have three comments.
Firstly, ClassicDrogn is correct about past tense being the expected thing for this kind of sequence. But, of course, people do work with present tense structure as well. That alone isn't a dealbreaker, really.
Secondly, you may also want to consider what perspective the scene is coming from. Third person omniscient narrator is all fine and well, but often even a third person sequence is still broadly following someone's point of view. If the intent is to paint a picture of the scene from the viewpoint of a theoretical audience member, listening to the speech, then you can play that aspect up more.
Conversely, you do have a bit at the end where the character - who's clearly the actual main character of this bit - speaking in an aside to an associate. They're saying something which isn't part of the main speech. This suggests that either you want a section break... that is to say, present the earlier 'speech' portion of the text more from the point of view of the audience, then the private conversation separately, from the character's perspective... or maybe rejig the entire speech section so it is from the character's own point of view. Still third person, mind you, if you like, but even third person omniscient can delve into the character's own thoughts.
Thirdly, it's also challenging to write a speech or public address. I'm not even talking about the actual content of it, here - I'm talking about presenting it to the reader in the context of the story. First of all, following strict grammar rules regarding use of quotation marks, open and closed inverted commas, this is not formatted correctly. If dialogue runs across multiple paragraphs, you should be ending paragraphs without a quotation mark, though the next paragraph of full dialogue would start with a quotation mark. Yes, this can look weird, but that is the rule.
One way around that problem, and also to break up the monotony of a speech, is to describe what the speaker is doing as they present their address. Leaning forward. Raising their voice at certain points. Gesturing. I'll link my own terrible fanfic at this point to illustrate what I mean - it's likely not the best example in the world, but it is what I have on hand.
