It is necessary to clean the images from noise, unnecessary dots, illogical lines, etc. The images are different. It is more difficult than that, it is easier... In general, to bring in a slightly more humane look than now. The hard part is that I would like to do this at GIMP. Advice on improving the coloring is welcome. Images 23.
P.S. The attached file is the most complex. The hand as you can see is cleaned... But these 23 images are just a couple of them.
