Edit your portrait image to Vector Image. a good choice if you need any gift, room decoration, wallpaper, etc.
The days take to finish is back to the how much detail or object on the image and the difficulty of the image.
its just for Standart image (Hair, Eye, Lips, Skin & Cloth) and I just vectorize only from head to half of the body (chest).
99% will look like the original Image.
You will get PSD/Ai file, so you can resize it to any size, change the color that you want, at the first I would ask the color of the objects that you want.
