I'm a professional dancer, my mum had a friend do an oil painting of a photo of me in a tutu and pointe shoes. It is large, about 70cm x 60cm. He is not professional, as in, he has another job and he does it as a side hobby. He has now tried charging us £900 for this piece. I was wondering if anyone knows roughly what it should be worth, as I believe I that £900 is completely ridiculous! Also, do I have any rights because it is a picture of me. He has it posted on Facebook for the world to see!
