I was basing my feedback off of what I remember most when I think poseidon, ie, the retail one with tiny tiny retail textures. You'll notice that there are no suggestions to cracks that end in the middle of nowhere (okay, fine, no suggestions to anything, really), and that those patterns were imagined in by whoever did the textures for the mvps. Personally, I feel the mediavps textures are a bit illogical and noisy already (though by no means ugly), and I was hoping that they'd receive a makeover this time around.
But I applaud your attention to detail. Looks pretty much spot on right now if copying the mvp textures was the goal in mind.
