Mechanical man, we meet again, eh? One of my favorite sources from the C&C soundtrack, and one of yours too, considering this is the second time I've seen you make an attempt at it.
Alright, the saw wave can work well for what it is, but you're going to need a deeper bass to cover that spectrum better. Either that or increase the bass in the current instrument, but I'm speaking from experience when I say that's really, really hard to do while keeping that distinct timbre and/or avoid the mids/highs from clipping to high hell.
My personal suggestion (and take this as what it is - a suggestion) would be to decrease (or even cut) the low end of the saw spectrum and add a deep (yet easy to manage) bass to the track. That gives you the best of both worlds - the very fitting saw and a deep, resonating bass that covers the low end well.
The beginning sounds like you're having a lot of fun toying with different timbre combinations. While all of them are fun, at 1:10 it feels that the track losses balance of where it should be. For the sake of track pacing you should change the section up about here - you can use the following ideas later in the track if/when you recapitulate the earlier material, so it doesn't sound repetitive. No need to waste the work you've already done - just use it a bit later.
Overall, I think some of your instruments (preferably the melodic ones) could use a little more attention to the high end of the spectrum. This will both make the overall sound more complete and make the themes easier to hear.
This is a great start to the track. I hope my suggestions come in handy for ya, since I really like the source.
