Use the contact form to arrange your anime portrait. Or email the artist at firstname.lastname@example.org or message them through Facebook or just use the secure PayPal form.
Portraits are usually completed within 1 to 3 weeks depending on how many portrait orders I have. Busiest times are after anime conventions and before Christmas. You will be given an estimate of how long each order will take. Just ask before ordering if you need the portrait in time for a special occasion such as a birthday or anniversary.
