Hair Color Correction: Achieving a Consistent Blonde Base - Professional Advice

Question
HI.  I am a professional hair stylist and have a color question.

My client came with with (SUPER thick) long blonde hair (which had only been patrial weaved.  SO the underneath and her regrowth was a level 7 with the rest being heavily weaved.  She brought in a picture of a REALLY blonde pixie where the base was colored as well.  She told me to error on the side of too blonde.  Here is the forumla I used:
Goldwell:

I first colored her roots with 40 volume 11P, Blonding Cream, and Blonding Cream ASH, Then weaved over the top Oxycur with 20volume.  I pulled down between the foils 11P and just Blonding cream feathering it down a bit.   

She said it is too blonde and says the top looks like I painted straight bleach on.  :(
What can I do?

Thanks
Hillary
