Really? That's crazy... it looks like the hair is more honey rather than warm-gray... but hey, if you say so! Your style is so unique and it's inspiring to see the range of shading and texture you can get with Copics. Do you any advice regarding coloring? Thanks!
Working with grayscale is fun. Our eyes interpret the grays as the actual color. My advice about coloring with markers is: experiment! Copic Sketch Markers have a brush tip that can create amazing textures. I also encourage full saturation. That's a good way to get a deep seamless color going. You can see some of my speed drawings on YouTube. I have at least 1 Copic video up at the moment: [link] Hope this helps!
