Some people were curious how I paint the black wings on my fantasy characters when I'm using ink, so here's how. Truth be told, It's fairly easier to do than it might seem, because the ink pretty much does half of the work for me. As you can see in the video, I first draw out the feathers with a pencil, and I use a bit of a heavy hand with that because those outlines will help when I do the colouring. I don't usually draw them super-neat, I mostly make sure to follow the right directions that the feathers would take on a wing and just go from there. Then, I take a small-ish soft brush and, with black calligraphy ink, I paint each feather at a time. The thing is, ink is a substance that's both quite dense (which is good because it is able to create texture just by layering the ink on top of itself) and not 100% opaque when used with a brush, for painting. At least not the one that I have been using anyway. Therefore, by painting each feather at a time and by using brush strokes that follow the shape and direction of each feather as well as with the help of the pencil outlines, I get a sort of 3D effect. After the first layer has dried, I usually go back and darken the areas that I want to be darker and thus giving the wing even more depth. Note that this is not what I do when I want to draw a realistic, bird-like wing. I usually employ this style only when I draw fantasy wings on fantasy, surreal characters that would not naturally have wings.
