I normally produce images at about A3 size, but can work larger or smaller if you prefer.

If I am painting a new artwork for you then I will give you an indication depending upon my current workload. I can be quite flexible and can shuffle jobs if something is needed in a hurry! If I give you a date I will stick to it...

The cost of a painting is almost entirely dependent upon the complexity of an image, so the cost will vary. It's worth remembering that an image can be simplified to reduce a cost!
