I think the final is, as has been mentioned, bold as hell. It's also a very consistent statement, and I don't think you can alter much without ruining it. That said, I don't much *like* it. I respect it, though.
The OOC one, though? That one I kinda like. It's completely different, all about muted pastels and soft light.
The composition feels, to my western eyes, vaguely related to an asian painting. It's probably just the reeds in the foreground which look like bamboo, and maybe something about the overall feeling of flatness in the perspective, or something. I feel like the muted tones and colors work better with that association for me than the popped neon look.
