So I've received advice, great advice, from great sources. All of these sources are greatly successful artists, doing essentially what I aspire to do. If I've learned anything from it, it's that I've wasted too much energy trying to figure out how to succeed.
In other words I'm far better off making images and chasing down the style and content I'm after, watching it develop into what ultimately becomes "my artistic voice".
That all sounds well and good, cheers (to an attempt to) live the dream. I'll keep on, keeping on, like a lunatic sawing off their arm, halfway through the bone. Faith and perseverance.
