Yeah the artwork is really cool and I think you should be proud of yourself!
Anyways, what I do is that I write the stories and everything that happens in them before making a profile. This also includes everything that happens in a fight scene because I enjoy them. I'd like to mention that relating to the topic, it's a good way of getting feats. While you're writing, feats will just randomly pop up in your head and heck, even listening to music can help me to come up with some really cool ideas
We may have debates on who would win involving your OCs, but the only characters my OCs will be fighting are the ones who that exist within their story so therefore anything that happens on the FCOC is completely non canon. So while I'm writing, I put vsdebating, tiers and any of that stuff aside.
Ok I actually do a bit of vsdebating with myself while writing fight scenes, especially if I want to apply some logic, avoid plot holes and stuff you know? It makes me wonder how less of them would exist if all action writers were professional vs debaters like us. But like Stan Lee said
"The person who'd win in a fight, is the person that the scriptwriter wants to win"
