Oh yeah @roy.batty. Familiar situation when customer needs quickly. My customers like my original style, but its important to them to get files for print, not the original work drawn by hand. After all, the original work costs more. On this most part of work staying with me)) , waiting for exhibition. I often work a gel pen - and not an ink pen, because I can by gel pen at home or in the workshop, or anywhere alse. Ink may leak and spoil many hours of work. Of course working with gel pen has its downsides - when you need to fill a lot of the surface (this is a very lengthy process), but finished work whith its texture shows the beauty of labor invested. Sometimes when Im not sure how to work out some detale or part of the picture (to make a mistake in the original can ruin all the work) in these cases, I certainly do copy and train on them. When the timing is very important - I draw basic elements, scan and collect them in the computer. But when such works delivered to the customer, I often return to them and finish the work without haste, for me own pleasure.
