This sounds pretty cool as a first-draft WIP, but it's got a lot holding it back if you're aiming for the OCR bar.
Opening is atmospheric, but you can totally make it even more atmospheric. Stretch that out, add some more ambient noises, really build up the suspense.
Once the strings come in, I can already tell what your main issue is going to be: samples. Really, this needs some higher quality samples (there are free ones out there that should do fine). Just spend some time hand-tweaking and really getting up to your waist with getting the sounds and sequencing just right. There's a lot of free soundfonts and soundpacks for synth1 (which is also free), so there's no excuse to not improve these!
The fake guitars are, like, REALLY fake. Recruit a real guitarist to give this some flavor. When doing guitars, it's very hard to get by without either getting a real guitarist or paying for a good sample pack like Shreddage.
Sequencing on everything is pretty stiff, most predominantly the synths and drums. Speaking of drums, they're quite muffled in this mix, so possible seek out another set (a set that would be great here is something like HardRockDrums.sf2. Again, just go out there and use google resourcefully and just try things out. You'll know when you've found a few winners cause they'll just start to really improve the mix.
This is also a bit on the repetitive side and never really gets going, so consider doing more with the arrangement to spice up the flow.
You've got a good base here, seriously. Just gotta get down and dirty with the "vamping"
