As an opening prologue, I quite like it. It does well at setting the tone for what is to come and the first encounter between the two forces. I must say I do also like how well it works with the pictures of the models that you included. I think it may have benefited from a proof read or two and maybe a tad more emphasis on where the theme fit in, but beyond that it more than does its job with ample to say.
Excellent.
