Wow... this is a very detailed picture, yet it appears so simple. You can clearly tell by a glance that these two people resent each other, and their appearances are very unique. The linart of the redhead's hair are smooth and accurate, although the lineart for the rest of his body could be smoothed out somewhat. I love how you drew and shaded the blouse of the spiky-haired (kind of) guy... it's simple, but elegant in its own way... although the shading could be improved. However, all in all, I love your shading technique, and your skill really shows in the color of the skin and the redhead's hair ^_^. Great job, great job~
