The first question customers usually ask is how much a drawing or painting will cost. The best answer I can give is an estimate, there being so many sizes of canvas available. The following list will give you a general idea.
All prices include postage within UK boundaries.
A4 pencil drawing £60
30cm x 30cm canvas £140 
45cm x 45cm canvas £240
50cm x 50cm canvas £275
(Each painting depends on the quality of reference supplied. Please contact me if you are interested in commissioning a painting to discuss prices further.)
