ryu-no-joou I hope you don't mind me asking, but was it difficult to draw? Like so that it would be the same size on each side? I'm tempted to do rdr characters with a print side and color back like yours.
Hi there! For the plain color back of the keychain, I first made a copy of the front side image, flattened it, and then flipped it horizontally. Then I made the flattened layer a selection, and filled in the selection on a separate layer with the fill color. Next, I made both the front side image and the filled/mirrored back side image separate PNGs with the same dimensions. I made the keychain through Wooacry, and their online mockup tools have the option to upload the front and back of the keychain. As long as the PNGs uploaded have the same dimensions, their mockup tool will align them automatically or notify you if something needs to be adjusted. Wooacry also prints using RGB vs. CMYK, and the image comes out the clearest at 300dpi. Hope this helps, and that's awesome that you're thinking of making some RDR keychains! :D
