Can anyone help me identify these paintings of a boy and a girl?

I recently found these paintings in an old shed and am wondering if anyone knows who painted them or how much they are worth? I don't know if I will be able to provide a picture or not, but one of them is of a boy with a green suit and he is standing up holding a violin or guitar. The other picture is of a girl standing up with her hands behind her back and she is wearing green and red checkered ballerina clothes. Both children have blonde hair. These are also painted on suede.
