When you purchase a painting you can choose from a few different sizes of canvas, and if you prefer a framework achromatic *, ** or polychrome and then you send a file, jpg, jpeg, PNP, or PDF, with the clear image and preferably color of the person you want to be painted a portrait.
* (A label to define the low saturation of colors style – much loved by MK)
** (with the use of colors with higher saturation, of course, always according to the particular taste of MK)
