Well, I usually use some references for my picture and this one was from a photo from the internet. People say she looks like Samantha Gainsford, as I don't know her nor was aware that the picture could be from someone famous I cannot really tell.If the original is still identifiable it seems I drew it not that bad. If that reference picture was from your friend and she finds it in any way offensive I'm of course obliged to take it down. Otherwise I'd be honoured to credit her properly in the picture description. Indeed a funny coincidence, given what an image dump the internet is that someone recognizes a particular face in a painted image from some random picture.
