2 extremely different sources, it'll be interesting to see how you mix 'em...
Track starting like a cowboy theme wasn't what I expected! The SoR bass line as a slower moody riff works great and the chords from EO2 work great as a trade-off. We return to SoR with a mass of guitars and then vocals enter as we alternate between the previous 2 sections. I really like the vocal delivery although I'd like the vocals themselves to be louder/more present, they get a tad drowned in the mix. There's moments like 2:08 where I'd like the vocals to explode but they just don't (maybe there's heavy compression on the vocal bus?). At 2:08 we get the pay-off of the previous 2 minutes with the SoR riff now delivered on heavy guitars and accompanied by a (loud) organ. I'm noticing at this point that the mastering is strange as it's not peaking too high (which a test on a DAW quickly confirms). We get another verse at 2:35 and then a guitar focused section at 3:00. I love the feel here but the mix is busy, maybe with more panning of the pieces it'd be easy to hear everything clearly. Interesting break at 3:57, a much needed variation to justify the length of the track! The guitar swells are a very cool idea. There's a drum transition, a cool nood to the SoR source and we repeat a previous section until the track ends.
On arrangement this is really cool, you grabbed 2 sources with completely different moods and feels and created a blend that has its also completely different mood and feel! Like proph said, there's a lot of swagger in here and it's really fun to listen to. Source usage is present throughout the entire track, so no issues there. I also feel SoR takes the main spot, thanks to how prominent the bass riff is on the arrangement.
On production this is generally great, drums sound great as do guitars and bass. I have some relatively minor qualms with the production tho, mainly on the mastering. Despite the rocking mood, the track generally feels quiet and I think it'd benefit from some extra compression/limiting on the master. Second is that the track is a bit heavy on the mids and could use some more highs as it currently ends up not sounding as crisp and punchy as one'd like. I made some quick EQ/limiting adjustments on my end as a test and I really liked how it sounded, but this is nowhere near a dealbreaker.
Overall, a really cool arrangement with solid production. My nitpicks are just that, this is an easy vote.
YES
