Not that I don't/won't give second accounts to people, but if you're okay with just the one, it's certainly easiest for me, and I think it makes more sense most of the time. For one, people can find all your stuff in a more obvious/single location.
On a side note, the pages from the prologue look very good art-wise. You definitely have improved over the years. Your style is something different than what I usually see. I can't put my finger on exactly what it is, but the combination of texture and color, along with the character styles being somewhere between realistic and cartoon. Anyway, it's looking good, so best of luck on it! :-)
