Great work so far, but I think you need to sort out a few things.
I think the cracks are overdone – unless this is a cracked vase that has been reassembled and glued together later. Also, the way they are made right now it looks more like deliberate scratchings over the vase other than actual cracks from broken pieces.
As for the texture itself it looks pretty good, but the cracks really detract from the overall piece.
Also, maybe you could fix some of the round edge normal problems in photoshop?
Keep up the good work!
