Very nice! I like her dark, gothic expression, and the bold coloring suits her very well. I love the sketchy look of the Big O in the background--you know, I haven't seen that show but once, so I can't comment too much on it, but I think it looks really good. I like the way you have the high contrast mixed with the pencil lines. But the buildings on the right side of the picture are really rather generic--they need more contrast, to match Big O on the other side. Without that, it makes the pic look slightly unbalanced, you know? Though I do not think they should have exactly as much contrast as Big O, since they are farther away... Ah, well. I love the simple colors. :)

WOW! This is a great picture! Dorothy was always pretty cool... her coolness is equally retained in the picture just like her animated counterpart on TV. Great job! I like how she stands out from the background too.

I really like the slight texture in the red you used. I'm a big fan of Big-O, so it's cool to see well-done fanart like this. Keep up the nice work!
