Bro! That's bad ass! And everything is coherent and consistent in the style. Nice use of foreground, midground and background. Even if it ain't colored, I'd still buy this book simply because its bad ass to look at and read. Well done.
Your last panel is my favorite rendition out of all the entries I've seen. Spacious with excellent depth, perspective, and movement. Stylistically reminds me of Hellsing a lot. Well done.
