I've missed them too, I doubt I'm alone either. It's probably my favorite art of yours. Well they look great, I hope you find the time to color it. As it's not colored I'm going to have to compare it to your existing, awesomely colored work, and give it a lower score.
Give me a simple black and white lineart (black being the lines and white being the areas to be colored) and I'll color the hell out of it, lol. I'll try to color this one, but of course I'm not as gifted at coloring as Rai, lol.
