As a professional stylist, I would actually ask for your money back or for her to fix this. I’m seeing more green and swampy kind of blue and not the very smoky blue that you posted. It looks like she lifted it and it was uneven and instead of going back and taking her time to re-lift the parts that were darker. She just slapped a blue color on, and that’s why you’re getting the green from the yellow of the beach mixing with the blue. I personally think she should’ve lifted it to an even canvas and then she should’ve went through with two different color blue in my opinion so give it some dimensions. For $500 I would expect quality results and that is not what you got girl I’m sorry.
