Did you morph the feet as well? It looks like the character is poking through the shoes as well in both the front and back. Did you test your morph with clothes on? Did you test how the morph looks when you do different poses? You still have lots to do on your morph before you start texturing, especially if you're considering selling it. It probably needs lots of JCMs and corrective morphs. I think you'll eventually find out that you generally will only make custom heads for only Poser characters and not full body morphs, because unless customers have Morphing Clothes or Poser Pro 2014, no one can use the morph with clothing.... though I'm guessing this morph is not made to have any clothes on.
