Yeah! you are right lightning seems a little wrong. I edited it a bit it seems ok now ..Both look nice. The lighting in the tag can be better, when you look at the render, the light is coming from above, yet your lightsource is down below. And the lower body can use some more blending.
Thanks !! I am glad you like it..I like the black/white signature more. Nice work!
Touka is my favorite character!
