Cookie, cookie, cookie - Sepia Experiement

An experiment in sepia-toning a comic.

One thing about my current art style I like is it's use of black boarders. I find them more appealing to work with and more in line with my art style. The problem is, manga convention as a very specific meaning attached to the boarders. White boarders are used to express the now, where as black boarders are used for flashbacks. I could understand doing this in a black-and-white context. I am, however, working in color. My idea is to maintain the same black boarders, but use sepia tones. The above is an experiement of turning a color comic into sepia.
