Group caricatures are a great way to mark an achievement, or milestone.
I charge 'per head' depending on the number of people involved, whether black and white, or colour, and the complexity of the scene.
I draw these on a tablet computer, and supply finished artwork on high quality photographic paper, or printed on a canvas frame, any size you like!
The process takes from a few days to a week.
I just need a set of photos to work from, and a description of the scene you'd like. I'll send you a sketch draft to approve, then a line drawing, and then finished artwork by email, and hard copy by courier.
