can we get a mix of both??

Your coloring is particularly noteworthy, so I'd hate to miss out on it.
I think if you did the comic mainly in B+W, but had a few full color splash pages here and there, that'd be a perfect compromise. You could have an increased length, since you're not coloring every single page, but then the more important panels that demand a full page to themselves could be in full color.
Or something along those lines.

We get to enjoy your coloring almost every day. And it's great, don't get me wrong there!. But I have to say I really liked the B&W from Cactus Attaxxx. My vote goes to B&W. And as some mentioned, B&W isn't about being lazy, it's about personal preference.

Now all I need to find out is how this Lulu works... (just read your journal about PayPal)

I'm not too fond of black and white stuff. I don't get why it's so popular in manga... It's understandable when it was first being made, since they probably used black ink, but now we've got computers and shit. To me, it's just lazy. Same with the right to left reading. It's not a rule, just tradition.
