Full size scanned and edited versions of the first three creatures for La última superviviente, first the individual drawings, and then a composition for a hypothetical book page. I started making two sketches per creature with the banshee, so the tragapieles is the only one with just one. Might add one more later so it doesn't look so lonely. It would be nice to make a sketchbook with these, I hope I can eventually.
For this kind of pieces I usually convert them to black and white images, edit them like that, and then I add a texture if it looks good, but I tend to use only grayscale a lot. This is how I like the images to look for myself, you'll see that the ig page has a heavier texture because that fits better with the context.
