Rain page 1 need help

Seeing as there's a fair bit more traffic here than at my blog, I'm imploring you all for help. I need help digitally colouring this. I really want to make this and two other pages work, but I'm not really sure how to go about doing it. If anyone has any tips or tutorials for digital colour that they tend to like to fall back on, could you point me in a certain direction (even a tutorial on DA, because I know there are a number of amazing ones floating around)

The other thing is how do YOU go about colouring a digital piece from sketchiness to finish. And what do you think I should do -- add finished lines, or make it a no line all shape piece.

Help guys. Please

Oh, and to see the progress or, should I say, how I want it to look, please check out my blog at
