The better quality the photo, the better quality the drawing. I am happy to work from any photos you have available, I can enhance and improve the quality of the image. I also specialise in adding details that aren’t visible in the original image.
A varying range of age and clarity shouldn’t hinder the quality of your finished portrait. If all the images are well lit and clear they will be drawn in the same style to look cohesive. I can add and remove aspects of individual photos to create the most consistent final piece.
