I've gone away from the texturing with watercolour-thing; once the novelty wore off it proved to be very messy and very time-consuming and I am already pressed for time, and the sort of colours and look I want is just not even attainable with traditional watercolour.
I've been trying to emulate a sort of watercoloury look and texture with my digital texturing and I am happy with the look, but again. You can't replace the real thing. My main worry is that this strays too far from what I described initially in my specification document.
Progress feels really slow right now.
