There are many variables in portrait pricing: the number of people, size of the painting, whether it is only head and shoulders, half or full length, background, etc. A 16"x20" single person, head and shoulders, simple brushed background starts at $700. It's roughly based on the size and time I think it would take me to paint it. Slightly smaller sizes are available, starting at $400. If it is from an existing photo, I must see it first to make sure there is sufficient detail and proper lighting; also if it is from a professional photographer I'd have to have written permission obtained by you to avoid copyright infringement. I prefer to take photos myself so the detail, lighting is right and I'd own the copyright. Shipping and frames are extra. Since every portrait is different I can't lock down prices until I know all the specifics. Hope this helps some.
Thank you for your inquiry!
