Thank you for your comment!
Yes, now that you point it out I guess so. I tried to keep on the safe side regarding the wrinkles. It was a present and a surprise and in those cases it might be preferable to polish things a bit. It might be a good challenge to make a portrait of an old person and really try to get the details right. I've made a portrait of myself, what I might look like in 40 years. Will post it later, please let me know what you think of it, if you have the time :)
