That source is way too poor for decent improvement.

@moondog777 I think it might be an improvement as the current image is from around 2014

thanks @Parker26

@Parker26, do take the time to look at cuts on a darker background. This one contains a lot of snow around the head, mostly due to the fact that it's pre-cut and pasted on a separate background by whoever did the original source. I've done the other source as I think it's got much better hair details.
