It would be my pleasure to paint a portrait for you, and there are lots of options to consider. Size, of course, is the first; think about where it would hang and make some measurements of available space. The sizes I have posted are without frames.
You can go with a more formal pose, or choose something more casual. Do you want to include a pet? Do you want a special setting? I would be happy to discuss these things with you and help you decide. We will start out with a setting-photo shoot.
I will select ones I feel would be most appropriate and make some rough sketches. Then I will submit my ideas to you to select the pose or poses you like best.
