I'd say the Casino Night rendition really rivals Cinossu's version. I love the extra swing and attitude you gave it, and the slight tweaks to the original notes make it sound more effective. It still seems very slightly lacking for some reason (...lead brass ensemble? A trumpet-trombone ensemble might sound kind of cool), but overall, you did an excellent job. The Chemical Plant rendition isn't exactly my favorite, but it's the first remix I've heard so far that makes really nice use of clavicords - they seem to fit perfectly in this song. I agree, the progressive volume really brings back the adrenaline rush of the original countdown... All it needs now is those high background strings.
