Yeah didn't notice that ORZ
I think it's a little funny how emoticons designed for lowercase characters shift when you swap them out for all caps. with [ orz ] you've just got the one arm visible placed against the ground (implied to be both arms in parallel), whereas [ ORZ ] in caps adds an arm at a downward angle sort of like they're mid-crawl (or perhaps another appendage, idk), and rounds out the body into a sort of shield-shaped chest. If I were to take an all caps version of [ orz ] taking lessons from how [ ORZ ] changes it, I'd probably do [ OPZ ] to maintain the single arm, while gaining the more rounded chest, that or [ OTZ ], taking inspiration from [ OTL ]
