I rearranged sketch in horizontal format and made additional changes. Also see the attached sequence of the work on the composition. I did all the illustrations in a vertical format, because it can contain a larger image area. I attached one of the made illustrations and the current one to compare.
Also I made the people birds in color. I added some tints in the plumage of the male. It looks more vivid and bright. I think need not to make too crooked legs and big buttocks for her, otherwise it looks ugly.
All this work and the changes took a lot of time. I would like to submit an invoice for the work done.
