Yeah, this is really short. I think prologues should be longer than just one paragraph but that's just my opinion.
Otherwise, I think you have a good start here. I mean, I haven't read any of your other prologues before this one so I can't really compare them (I'll just take your word for it that this one is better )
Anyway, I believe you could lengthen this out so that it is longer and maybe squeeze in some more descriptions so that I can imagine what is going on in the scene. I can't really picture your main character from this.
Umm, that's really all I can come up with right now. Keep Writing
