I'm going to be ultra-honest with you because I love the Zero Wing music.
This is poop.
Workshop is definitely the place to hang around if you want to eventually be an OC Remixer. To be brief, your sounds are very basic and sound retro as a result. It's not necessarily a bad thing, but it can be for OCR. The drums are very underwhelming and are not varied much at all. I can't hear too much to them other than the kick and snare, the hats are ridiculously quiet. And to top it all off, this is pretty much a straight cover. You need to personalize the song a bit more for OCR. You do this by writing some original parts, maybe a solo here and there, and mingle original bits with bits from the source. The guitar rhythm is pretty cool, but it should be doubled and hardpanned to each side. I think a lot of work needs done with this before you could consider subbing it to OCR, but keep at it!
