Of course, with a copier, you can reproduce anything in any size you like- and you may be a painter of considerable parts- but I would vote for a simpler presentation of the arms- maybe only the lion on the shield, no helm, no bordure, no mantling at all. But, speaking of that helm, might it not be supposed to be on a torse? "Or" ( ha) if that is a torse, ought it also not have two colors?
