Arsheesh really hit the nail on the head with that. You can't diminish the value of color on the mood of a piece.
I think you could make one hand drawn piece look a number of different ways based on how you chose to color and texture it.
How saturated or desaturated the colors, if a dirty gritty texture or parchment background is used.
I don't think there's anything wrong with your drawing style - it's just a bit harder to get gritty from black and white, especially when done as traditional work.
It can be done with B&W but it will require a LOT more work. More dark black, like black seas, lots of shadow and little sketchy texture lines and dots.
It's far easier to do that stuff as post-process work in an image editor.
