Awesome piece! I love your style man, I really enjoy the modern take on orchestra by adding in guitars, subbing bass guitar, and the drum set. I think you definitely have a future in game music if you really go for it. The thing holding you back is your sound samples, which you stated, but once you get a sequencer you can import all of your midi pieces into it for a huge head start in bringing these more to life.
I really like how you have more difference in texture with this one, like the string and wind interplay section (you could have done that with guitars too :P). It was a great change for the listener from the tutti passages. I also really like that you worked out the drum parts. I know those can be really tedious and a pain to notate out (although maybe bar 28 is impossible with 3 toms? Dunno, hard to hear). Love the section with just open and closed hi hats. Cool drum change. You always have a way of ending your pieces with such a cool chord, stuff I never think of doing but I really dig it. I need to tear that page out of your playbook 😄
One thing I would keep focused on is that overall texture. It's way better then some other pieces I've heard from you, but keep exploring different combinations with the instruments! There were plenty of times you could have removed some of the instruments in the tutti sections to really let the other instruments be heard. For instance, I wouldn't have even known there was an acoustic guitar without looking at the score.
And speaking of, I'm a guitarist so I'll comment on the guitars a bit.
1. Maybe have the bass guitar with the other guitars in your score? I think it would be easier to follow with it being in it's instrument "family"
2. I noticed at the end you gave the strings vibrato for the last chord. Why not the guitars? We can vibrato too bruh. In fact, Your main melody was begging for it. I'm not a fan of long sustained notes with no vibrato. Even if it's just subtle, which is what I do most of the time anyway, it can really make those notes soar and sing. And EVEN if your notation software doesn't play it back, it would be good to indicate it. Then again, it could be up to the performer to do it liberally.
3. Are the overdriven guitar power chords supposed to be palm muted for the staccato markings? I would write p.m. with a dashed line over the indicated parts if they are. It'd sound better imo anyway.
4. Watch for playability in the acoustic guitar at bar 49, those notes are high up there and depending on if the guitar has a cutaway may be impossible. It might be better to drop that down an octave or give it to an electric.
5. I know you're writing for musescore playback, but keep in mind the electric guitars can switch from distortion to clean to wah sounds to alien languages with their pedals. You could have one electric guitar part go back and forth between clean arpeggios then to the main melody or whatever. Again, I know you're writing for playback, but if you ever were in the position to have performances of these pieces, something to consider.
6. This is my biggest point. I want you to imagine the lead guitar part being played at the piano. Would you write for it differently? What I'm saying is take advantage of the guitar being a polyphonic instrument. Yeah I know you give it chords sometimes, but what if you played the main melody, and did a repeat with thirds? Or even octaves to really cut through the orchestra? You have a lot of potential with the instrument, and I think you could open up a lot more possibilities with your already-great-writing by exploring the instrument more.
I know you're going for a certain sound with your music, and like I said, I really dig the orchestra plus rock band. But when I was in school, we constantly had to write for small ensembles, forcing ourselves to squeeze every last timbre out of the instruments, and really getting acquainted with what they were capable of. You've got loads of talent, and possibly more importantly, and consistent and ever evolving dedication to your craft. Keep learning, keep studying, keep writing for instruments you're unfamiliar with, because, well, that's like the whole purpose of posting here imo.
I'm excited to hear what's coming next from you; I'll always look out for new pieces from you. Nice work here, I love how your music continues to improve!
