    Three pictures of a person bending sheet metal (steel) will be supplied for one caricature to be drawn. The end result in the finished product will be the person holding steel while the press brake remains in the image. Summary - take three photos for reference of a person bending steel and make one image from the three pictures. The three pictures are just for reference of what may work best, angles. The face of the person needs to be clearly visible. As I do custom metal fabrication, the plan is to use the end result with the catchphrase - "We brake it, you buy it :)" The word brake in this instance means the bending of steel.
