Refining the Cover Image Characters

With a big cover image of 8000x4000 pixels, I enough resolution to add some detail to my otherwise cartoonish characters. I figure that the cover image will be printed at 300 DPI or higher, making even mintue details like eyelashes crisp and visible. I can imagine a reader poring lovingly over the image and noticing Momma Jay’s eyelashes, or noticing that the two brown mice are wearing argyle socks. In the picture below I’ve extracted the Momma Jay charter from the cover picture so that I can work on the image without distractions. The trick will be to maintain her proportions so that she’ll look right when I paste the her back into the main image.
