How to get the wrinkles out of my loft

For quite some time now I've been working on trying to get the wrinkles out this boot and I just can't get rid of the wrinkles. In some of the upper level sketches there are pictures imbedded of a boot that I am trying to replicate so I have guide curves set up to match the profile with a lot of sketches in between to help define the profile more. Would you be able to take a look and it and see what I am doing wrong?
