I see what you're getting at and what you mean by what this work is suppose to mean to you and your SO, but please try to get a response from Cashoo. Tell her you're dissatisfied and feel as if she will not finish your work in a timely fashion; therefore you've foind an artist willingly to finish what she will not, and you want permission to get it done.

She either gives you A) permission or B) the work and has a week to do so.
