A portrait similar to the one above takes me around 2-3 days, so therefore I suggest a price point of £150 plus shipping; this example included the original artwork and a 40x30cm mount. Mounts are included as standard.
Frames are generally not included purely to reduce shipping costs, though they can happily be sourced and included to suit requirements.
*Any variations on pricing due to size, subject or framing would be agreed upon in advance of any commission and adhered to.
