I wish it were as easy as saying this size costs x and that size costs y, but full-color paintings are a lot more complicated than that (as you can imagine). There are many factors: background, and subject matter, and the complexity of everything from hands, clothing, and other objects or people in the picture.
That means you’re going to have to do something you might not like and contact me directly. Yikes! I know it can be awkward and uncomfortable, but I’m quite friendly and I’ll try to make it as simple as possible.
What I can tell you is that the price is likely to start around $400 for an 11×14 painting with the simplest of background, one person, and then only the head and shoulders.
I hope that helps give you a rough idea – the only way to know more is to send me a message!
